Description
Features
The HCPL-261A family of optically coupled gates shown • HCMOS/LSTTL/TTL performance compatible
on this data sheet provide all the benefits of the in-
dustry standard 6N137 family with the added benefit
• 1000 V/µs minimum Common Mode Rejection (CMR)
at VCM = 50 V (HCPL-261A family) and 15 kV/µs
of HCMOS compatible input current. This allows direct
minimum CMR at VCM = 1000 V (HCPL-261N family)
interface to all common circuit topologies without ad-
• High speed: 10 MBd typical
ditional LED buffer or drive components. The AlGaAs
LED used allows lower drive currents and reduces • AC and DC performance specified over industrial
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.
temperature range -40°C to +85°C
