Guaranteed operation at low input currents

and the high current transfer ratio (CTR) reduce

the magnitude and effects of CTR degradation.

this device extremely useful in applications where a high

CC andVO specifica-

tions and by testing output high leakage (I

OH) at 18 V.

mA and have a 7 V V

CC and VO rating. The 300% minimum

CTR allows TTL to TTL interfacing at this input current.

Important specifications such as CTR, leakage cur-

rent, and output saturation voltage are guaranteed

over the 0°C to 70°C temperature range to allow

trouble-free system operation. Selection for lower in-

put currents down to 250 µA is available upon request.
