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 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.
