Avago Technologies has added to its family of high-speed dual-supply voltage digital CMOS optocouplers with the ACPL-W70L and ACPL-K73L digital CMOS stretched optocouplers which operate at dual supply voltages of 3.3 and 5V at a minimum speed of 15MBaud.

These optocouplers are designed provide up to 5kV isolation voltage protection and to achieve lower propagation delay (55ns max.) and pulse width distortion (25 ns max.) with the additional glitch-free power-up feature. This feature outputs low voltage logic during power loss and provides output logic that corresponds to the input voltage when the power supply recovers.

The ACPL-W70L/K73L series targets designers of power supply, industrial, consumer, and test and measurement applications.

The single channel ACPL-W70L and two channel ACPL-K73L come in SSO-6 and SSO-8 packages respectively. Both can operate in a wide operating temperature range from -40 to 105 deg C.
