7486 OR Gate IC

The TL494 device incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application. The TL494 device contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits.The TL494C device is characterized for operation from 0C to 70C. The TL494I device is characterized for operation from 40C to 85C.

Optocoupler 817 QUAD contains an IRED optically coupled to a phototransistor. It is packaged in a 4pin DIP, available in wide-lead spacing option and SMT gullwing lead-form option. Input-output isolation voltage(rms) is 5.0kV. Collector-emitter voltage is 80V(*) and CTR is 50% to 600% at input current of 5mA.
