Low operating power 5MBd digital optocouplers from Avago

Avago Technologies has announced the ACPL-M21L/021L/024L/W21L/K24L optocoupler family. The ACPL-x2xL optocouplers are designed to meet customer needs for lower power, higher isolation voltage, and better common mode rejection (CMR) performance.

The digital optocouplers are used in a variety of isolation applications ranging from power supply and motor control circuits to data communications and digital logic interface circuits.

The new ACPL-x2xL 5MBd digital optocouplers require minimum LED drive current of 1.6 mA, and detector IC power consumption of less than 1.1 mA. The detector IC contains a CMOS output stage with glitch-free output during power-up and power-down, and optical receiver input stage with built-in Schmitt trigger that provides logic compatible waveforms, eliminating the need for additional wave shaping. An internal shield also guarantees high common mode rejection (CMR) of minimum 25 kV/µs at1000V common mode voltage. ACPL-x2xL optocouplers operate at 3.3V/5V power supply with AC and DC performance from an extended temperature range of -40°C to +105°C.

The ACPL-M21L, ACPL-021L and ACPL-W21L are single channel optocouplers in 5-lead small-outline (SO5), 8-lead small-outline (SO8) and stretched 6-lead small-outline (SO6) packages, respectively. Whereas, the ACPL-024L and ACPL-K24L are dual channels optocouplers in 8-lead small-outline (SO8) and stretched 8-lead small-outline (SO8) packages, respectively.

These devices are compliant to industrial safety standards such as IEC/EN/DIN EN 60747-5-5 approval for reinforced insulation, UL 1577 and CSA.

ACPL-M21L is immediately available in sample quantities, and is priced at $0.88 each in lots of 10k units.
