The IC CD4026 is an IC which can perform the function of both a counter as well a 7-segment Driver. One single IC can be used to count form zero (0) to nine (9) directly on a Common Cathode type 7-segment display. The count can be increased by simply giving a high clock pulse; also more than one digit (0-9) can be created by cascading more than one CD4026 IC. So if you have a 7-segment (CC) display on which you have to display numbers that are being counted based on some condition then this IC will be a perfect choice.
The CD4050 hex buffers are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors. These devices feature logic level conversion using only one supply voltage (VDD). The input signal high level (VIH) can exceed the VDD supply voltage when these devices are used for logic level conversions. These devices are intended for use as hex buffers, CMOS to DTL/ TTL converters, or as CMOS current drivers, and at VDD = 5.0V, they can drive directly two DTL/TTL loads over the full operating temperature range.
The 4077 is a quad 2-input EXCLUSIVE-NOR gate. The outputs are fully buffered for the highest noise immunity and pattern insensitivity to output impedance. The 4077 operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
The CD4081 quad gate is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement mode transistors. They have equal source and sink current capabilities and conform to standard B series output drive. The devices also have buffered outputs which improve transfer characteristics by providing very high gain. All inputs protected against static discharge with diodes to VDD and VSS.
DS1302 is a tickle-charge timekeeping chip which contains a real-time clock/calendar and 31 bytes of static RAM. DS1302 uses serial communication to interact with microcontrollers. Also, it automatically adjust the date for the month with fewer days. Clock operates in 24hr or 12hr format with an AM/PM indicator. DS1302 chip is also commonly used as DS1302 RTC module which comes with a 32 kHz crystal and on-board battery backup all in a small SIP module that is compatible with a breadboard. DS1302 module are used by makers with Arduino, Raspberry Pi and other Micro-controllers.
The DS1307 serial real-time clock (RTC) is a lowpower, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.

The HEF4104B is a quad low voltage-to-high voltage translator with 3-state outputs. It provides the capability of interfacing low voltage circuits to high voltage circuits. For example low voltage Local Oxidation Complementary MOS (LOCMOS) and Transistor-Transistor Logic (TTL) to high voltage LOCMOS. It has four data inputs (A0 to A3), an active HIGH output enable input (OE), four data outputs (B0 to B3) and their complements (B0 to B3).
The HT12E Encoder ICs are series of CMOS LSIs for Remote Control system applications. They are capable of Encoding 12 bit of information which consists of 8 address bits and 4 data bits. Each address and data input is externally programmable or fed in using switches. The HT12D Decoder ICs are series of CMOS LSIs for Remote Control system applications. These ICs are paired with each other. For proper operation a pair of encoder/decoder with the same number of address and data format should be selected (HT12E is paired with HT12D). The Decoder receive the serial address and data, transmitted by a carrier using an RF transmission medium and gives output to the output pins after processing the data. These Ics have operating Voltage : 2.4V ~ 12V. They have Low Power and High Noise Immunity.
This is a IC Socket/Base for 28 pin SMD PLCC IC. This is a SMT base and is advisable on boards with point to point wiring because replacing a defective IC is time consuming and can possibly damage your prototype board. The use of an IC socket is inexpensive compared to the time and effort required to replace an IC chip. IC sockets also reduce the possibility of damaging the board when swapping out IC’s.

LM386 is a widely used audio amplifier IC manufactured in 8 pin dip, VSSOP, SOIC and other packages. The IC is basically designed for low voltage commercial applications, apart from commercial applications it is also a famous IC among electronic hobbyists and experimenters. The internal gain of the IC is set to 20 but it can be adjusted by connecting a resistor and a capacitor in series between the pin number 1 and 8, by this procedure the user can adjust the gain between 20 to 200. Due to the small size, low quiescent current and low voltage requirements this IC is ideal to use in wide variety of portable battery operated applications and devices.
The LM741 series are general-purpose operational amplifiers which feature improved performance over industry.The amplifiers offer many features : overload protection on the input and output, no latch-up when the common-mode range is exceeded, as well as freedom from oscillations.
