Description

The HCPL-261A family of optically

coupled gates shown on this data

sheet provide all the benefits of the

industry standard 6N137 family

with the added benefit of HCMOS

HCPL-261A HCPL-061A

HCPL-263A HCPL-063A

HCPL-261N HCPL-061N

HCPL-263N HCPL-063N

compatible input current. This

allows direct interface to all

common circuit topologies without

additional 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 detector 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 immunity

of 1000 V/

µs for the HCPL-261A

family and 15000 V/

µs for the

HCPL-261N family.

The connection of a 0.1

µF bypass capacitor between pins 5 and 8 is required.
