ACFL-6212U-560E

Overview

The ACFL-6212U-560E is a dual-channel high-speed optocoupler from Broadcom’s R²Coupler series, housed in a 12-SO surface-mount package. It features push-pull logic outputs with a data rate of 15 Mb/s and propagation delays of 100 ns maximum. The device provides 5000 Vrms isolation voltage and a common-mode transient immunity of 25 kV/µs. It operates within a temperature range of -40°C to +125°C, supports a forward current of 20 mA, and requires a supply voltage between 3V and 5.5V.

Feature Summary
