The Broadcom® 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.
