Guaranteed operation at low input currents
and the high current transfer ratio (CTR) reduce
the magnitude and effects of CTR degradation.
The outstanding high temperature performance of this split
Darlington type output amplier results from the inclusion
of an integrated emitter-base bypass resistor which shunts
photodiode and rst stage leakage currents to ground.
The HCPL-2731/0731 have a 400% minimum CTR at an input
current of only 0.5 mA making it ideal for use in low input cur-
rent applications such as MOS, CMOS, and low power logic
interfacing or RS232C data transmission systems. In addi-
tion, the high CTR and high output current capability make
this device extremely useful in applications where a high
fanout is required. Compatibility with high voltage CMOS
logic systems is guaranteed by the 18 V V
CC
and V
O
specica-
tions and by testing output high leakage (I
OH
) at 18 V.
The HCPL-2730/0730 are specied at an input current of 1.6
mA and have a 7 V V
CC
and V
O
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.
