Data Sheet

The connection of a 0.1

µF bypass capacitor between pins 5 and 8 is

required.

Description

The HCPL-261A family of optically coupled gates shown

on this data sheet provide all the benefits of the in-

dustry standard 6N137 family with the added benefit

of HCMOS compatible input current. This allows direct

interface to all common circuit topologies without

additional LED buffer or drive components. The Al-

GaAs LED used allows lower drive currents and reduc-

es degradation by using the latest LED technology. On

the single channel parts, an enable output allows the de-

tector to be strobed. The output of the detector IC is an

open collector schottky-clamped transistor. The internal

shield provides a minimum common mode transient im-

munity of 1000V/

µs for the HCPL-261A family and 15000

V/

µs for the HCPL-261N family.
