Low Power, 5-MBd Digital CMOS Optocoupler
Data Sheet
Description
Features
Broadcom® ACPL-M21L (single-channel SO-5 package),
ACPL-021L (single-channel SO-8 package), ACPL-024L
(dual-channel SO-8 package), ACPL-W21L (single-channel
stretched SO-6 package), and ACPL-K24L (dual-channel
stretched SO-8 package) are optically coupled logic gates. The
detector IC has CMOS output stage and optical receiver input
stage with built-in Schmitt trigger to provide logic-compatible
waveforms, eliminating the requirement for additional
waveshaping.
CMOS output
Wide supply voltage: 2.7V to 5.5V
Low power supply current I : 1.1 mA/channel max.
DD
Low forward current I : 1.6 mA min.
F
Speed: 5 MBd typ.
Pulse width distortion (PWD): 200 ns max.
Propagation delay skew (tpsk): 220 ns max.
Propagation delay (tp): 250 ns max.
Common mode rejection: 25 kV/μs min. at V = 1000V
An internal shield on the ACPL-M21L/021L/024L/W21L/K24L
guarantees common mode transient immunity of 25 kV/μs at a
common-mode voltage of 1000V. The ACPL-x2xL optocouplers'
series operates from a 2.7V to 5.5V supply with guaranteed AC
and DC performance from an extended temperature range of
–40°C to +105°C.
CM
Hysteresis: 0.2 mA typ
Temperature range: –40°C to +105°C

tPHL propagation delay is measured from the 50% (Vin or IF) on the falling edge of the input pulse to the 50% VDD of the falling edge of the VO signal. tPLH
propagation delay is measured from the 50% (Vin or IF) on the rising edge of the input pulse to the 50% level of the rising edge of the VO signal.
b. PWD is defined as |tPHL – tPLH|.
c.
tPSK is equal to the magnitude of the worst case difference in tPHL and/or tPLH that will be seen between units at any given temperature within the
recommended operating conditions.
d. CMH is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in a high logic state.
e. CML is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in a low logic state.
NOTE Use of a 0.1 μF bypass capacitor connected between V and ground is recommended.
