Description
Features
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 need for additional waveshaping.
• CMOS output
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 1000 V. The ACPL-x2xL
optocouplers' series operates from a 2.7 V to 5.5 V
supply with guaranteed AC and DC performance from an
extended temperature range of -40 °C to 105 °C. Glitches
free output upon power-up and power-down of optocoupler.
• Propagation delay (tp): 250 ns max

Notes:
1. 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
2. PWD is defined as |tPHL - tPLH|
3. 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.
4. 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.
5. 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.
6. Use of a 0.1 μF bypass capacitor connected between Vdd and ground is recommended.
