Description
Features
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 ad-
ditional LED buffer or drive components. The AlGaAs
LED used allows lower drive currents and reduces
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 1000 V/µs for the HCPL-261A family and 15000
V/µs for the HCPL-261N family.
