Low-Power 10-MBd Digital CMOS Optocouplers
Data Sheet
Description
Features
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
common-mode 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.
Low IDD current: 1.3 mA/channel maximum
Low input current: 1.6 mA
Built-in slew-rate controlled outputs
20 kV/μs minimum Common-Mode Rejection (CMR) at
VCM = 1000V
High speed: 10 MBd minimum
Guaranteed AC and DC performance over wide
temperature: –40°C to +105°C
Wide package selection: SO-5, SO-8, stretched SO-6, and
stretched SO-8
