Data Sheet
Description
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 specication
up to 15,000 V/µs at V
cm
= 1000 V.
This unique design provides maximum AC and DC circuit
isolation while achieving TTL compatibility. The optocou-
pler AC and DC operational param e ters are guaranteed
from -40 °C to +85 °C allowing troublefree system per-
formance.
