HCPL-2731-000E

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
current application, such as MOS, CMOS, and low-power logic interfacing or RS232C data transmission systems. In
addition, 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 18V VCC and VO specifications
and by testing output high leakage (IOH) at 18V.
The HCPL-2730/0730 are specified at an input current of 1.6 mA and have a 7V VCC and VO rating. The 300% minimum
CTR allows TTL to TTL interfacing at this input current.
Important specifications, such as CTR, leakage current, and output saturation voltage, are guaranteed over the 0°C to 70°C
temperature range to allow trouble-free system operation. Selection for lower input currents down to 250 µA is available upon
request.
