Low-Power 10-MBd Digital CMOS Optocouplers
Description
Features
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.
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
Package selection: SO-5, SO-8, stretched SO-6, and
stretched SO-8

ACPL-064L, ACPL-M61L, ACPL-W61L, ACPL-K64L Data Sheet
Typically, the output slew rate (rise and fall time) varies with
the output load, as more time is required to charge up the
higher load. The propagation delay and the PWD both
increase with the load capacitance. This will be an issue
especially in parallel communication because different
communication lines will have different load capacitances.
However, optocoupler ACPL-x6xL has a built-in slew-rate
controlled feature to ensure that the output slew rate
remains stable across wide load capacitance. Figure 13
shows the rise time and fall time for ACPL-x6xL at 3.3V and
5V.

A peaking capacitor can be placed across the input currentlimit resistor (Figure 14) to achieve enhanced speed
performance. The value of the peaking capacitor is
dependent on the rise and fall time of the input signal,
supply voltages, and LED input driving current (IF).
Figure 15 shows significant improvement of propagation
delay and pulse width distortion with an added peak
capacitor at a driving current of 2 mA and 3.3V/5V power
