Description
Features
• 15 kV/µs minimum Common Mode Rejection (CMR)
at VCM = 1 kV for HCNW2611, HCPL-2611, HCPL-4661,
HCPL-0611, HCPL-0661
• High speed: 10 MBd typical
• LSTTL/TTL compatible
• Low input current capability: 5 mA
• Guaranteed AC and DC performance over temper-
ature: -40 °C to +85 °C
The 6N137, HCPL-26xx/06xx/4661, HCNW137/26x1 are
optically coupled gates that combine a GaAsP light emit-
ting diode and an integrated high gain photo detector.
An enable input allows the detector to be strobed. The
output of the detector IC is an open collector Schottky-
clamped transistor. The internal shield provides a guar-
anteed common mode transient immunity specification
up to 15,000 V/µs at Vcm = 1000 V.
This unique design provides maximum AC and DC circuit
isolation while achievingTTL compatibility. The optocou-
pler AC and DC operational parameters are guaranteed
from -40 °C to +85 °C allowing troublefree system per-
formance.
• Available in 8-Pin DIP, SOIC-8, widebody packages
• Strobable output (single channel products only)
• Safety approval
