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 benets of the in-
dustry standard 6N137 family with the added benet
of HCMOS compatible input cur rent. This allows direct
interface to all common circuit topologies without
additional LED buer or drive components. The Al-
GaAs LED used allows lower drive currents and reduc-
es degradation by using the latest LED tech nol ogy. 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 mini mum common mode transient im-
munity of 1000 V/µs for the HCPL-261A family and 15000
V/µs for the HCPL-261N family.
