HCPL-4731-000E

The HCPL-4731-000E is a 2-channel 8-pin very low power consumption High Gain Optocoupler designed for use in CMOS, LSTTL or other low power applications. It can be driven with an input current as low as 40µA and has a typical current transfer ratio of 3500%. This high gain coupler uses an AlGaAs LED and an integrated high gain photodetector to provide an extremely high current transfer ratio between input and output. Separate pins for the photodiode and output stage results in TTL compatible saturation voltages and high speed operation. It is especially well suited for ISDN telephone interface and battery operated applications due to the low power consumption. A 700% minimum current transfer ratio is guaranteed from 0 to 70°C operating temperature range at 40µA of LED current and VCC ≥ 3V.

• Will operate with VCC as low as 1.6V
• 40µA Ultra low input current capability
