Broadcom ACPL-W61L-500E

The low-power ACPL-x6xL digital optocouplers combine an AlGaAs light emitting diode (LED) and an integrated high gain photodetector. The optocoupler consumes low power, at maximum 1.3 mA IDD current per channel across temperature. With a forward LED current as low as 1.6 mA, most microprocessors can directly drive the LED. An internal Faraday shield provides a guaranteed commonmode transient immunity specification of 20 kV/μs. Maximum AC and DC circuit isolation is achieved while maintaining TTL/CMOS compatibility. The optocouplers' CMOS outputs are slew-rate controlled and designed to allow the rise and fall time to be controlled over a wide load-capacitance range. The ACPL-x6xL series operates from both 3.3V and 5V supply voltages with guaranteed AC and DC performance from -40°C to +105°C. These low-power optocouplers are suitable for high-speed logic interface applications.
