SAN JOSE, Calif., May 25, 2012 — The ACPL-M21L/021L/024L/W21L/K24L optocoupler family has been announced by Avago Technologies. The 5-MBd digital optocouplers consume <10 mW per channel, handle isolation voltages of up to 5 kV and offer good common-mode rejection (CMR) performance, thanks to the new LED and detector integrated circuit (IC) design.
Isolation applications range from power supply and motor control circuits to data communications and digital logic interface circuits.
They require a minimum LED drive current of 1.6 mA and detector integrated circuit power consumption of <1.1 mA. The detector IC contains a CMOS output stage with glitch-free output during power-up and power-down, and an optical receiver input stage with a built-in Schmitt trigger that provides logic-compatible waveforms, eliminating the need for additional wave shaping. An internal shield guarantees minimum CMR of 25 kV/µs at 1000-V common-mode voltage. The devices operate from a 3.3-/5-V power supply with guaranteed AC and DC performance at a temperature range of −40 to 105 °C.
The ACPL-M21L, ACPL-021L and ACPL-W21L are single-channel optocouplers in 5-lead small-outline, 8-lead small-outline, and stretched 6-lead small-outline packages, respectively. The ACPL-024L and ACPL-K24L are dual-channel devices in 8-lead small-outline and stretched 8-lead small-outline packages, respectively.
- Schmitt trigger
- Oscilloscope electronic circuit that produces an output pulse whose pulse width is determined by the time that the output voltage exceeds a specified level.
