The HCPL2631 is a dual optocoupler designed for use in high-speed digital interfacing applications that require high-voltage isolation between the input and output. Applications include line receivers, microprocessors or computer interface, and other control systems.
Each channel of the HCPL2631 optocoupler consists of a GaAsP light-emitting diode and an integrated light detector composed of a photodiode, a high-gain amplifier, and a Schottky-clamped open-collector output transistor. An input diode forward current of 5 mA will switch the output transistor low, providing an on-state drive current of 13 mA (eight 1.6-mA TTL loads).
The device is mounted in a standard 8-pin dual-in-line plastic package. The internal shield provides a guaranteed common-mode transient immunity of 1000 v/us minimum.
The HCPL2631 is characterized for operation over the temperature range of 0°C to 70°C.
