H74A1

The H74A1 is designed as one kind of GaAs infrared emitting diode and NPN silicon photo-transistor that can provides logic optical interfacing of TTL gates with guaranteed level compatibility in practical specified circuits. This device is a transistor output photo-coupled isolator specifically designed to eliminate ground loop cross talk and reflection problems when two distinct logic systems are coupled.

The absolute maximum ratings of the H74A1 can be summarized as:(1)power dissipation: 100 milliwatts;(2)forward current (continuous): 60 milliamps;(3)forward current (peak): 3 ampere;(4)reverse voltage: 6 volts.
