FEATURES

• Very high speed-10 MBit/s

• Superior CMR-10 kV/µs

• Double working voltage-480V

• Fan-out of 8 over -40°C to +85°C

• Logic gate output

• Strobable output

• Wired OR-open collector

• U.L. recognized (File # E90700)

DESCRIPTION

The 6N137, HCPL-2601/2611 single-channel and HCPL-2630/2631 dual-channel

optocouplers consist of a 850 nm AlGaAS LED, optically coupled to a very high

speed integrated photodetector logic gate with a strobable output. This output

features an open collector, thereby permitting wired OR outputs. The coupled

parameters are guaranteed over the temperature range of -40°C to +85°C. A

maximum input signal of 5 mA will provide a minimum output sink current of 13

mA (fan out of 8).

An internal noise shield provides superior common mode rejection of typically 10

kV/µs. The HCPL- 2601 and HCPL- 2631 has a minimum CMR of 5 kV/µs.

The HCPL-2611 has a minimum CMR of 10 kV/µs.

APPLICATIONS

• Ground loop elimination

• LSTTL to TTL, LSTTL or 5-volt CMOS

• Line receiver, data transmission

• Data multiplexing

• Switching power supplies

• Pulse transformer replacement

• Computer-peripheral interface
