ACPL-177KL-200

Transistor, Photovoltaic Output Optoisolators Overview

The ACPL-177KL-200 is a high-reliability Class K quad-channel optocoupler manufactured by Broadcom Limited. It features a 16-pin ceramic DIP package with sealed construction, designed for operation across the full military temperature range of -55°C to +125°C. The device provides four independent channels, each utilizing a GaAsP LED coupled to a high-gain photodetector with an open-collector output stage. It operates at a supply voltage as low as 3.0V and delivers a minimum current transfer ratio of 300% at an input current of 0.5mA. The unit offers an isolation voltage of 1500Vdc and complies with MIL-PRF-38534 standards.
