CAUTION: It is advised that normal static precautions be taken in handling and assembly of this

component to prevent damage and/or degradation which may be induced by ESD.

Description

The HCPL-2200/2219 are optically coupled logic gates

that combine a GaAsP LED and an integrated high gain

photo detector. The detector has a three state output

stage and has a detector threshold with hysteresis. The

three state output eliminates the need for a pullup

resistor and allows for direct drive of data busses. The

hysteresis provides differential mode noise immunity

and eliminates the potential for output signal chatter.

A superior internal shield on the HCPL-2219 guarantees

common mode transient immunity of 2.5 kV/

µs at a

common mode voltage of 400 volts.

The Electrical and Switching Characteristics of the

HCPL-2200/2219 are guaranteed over the tempera-

ture range of 0

with TTL, LSTTL, and CMOS logic and result in lower

power consumption compared to other high speed

optocouplers. Logic signals are transmitted with a

typical propagation delay of 160 nsec.

The HCPL-2200/2219 are useful for isolating high

speed logic interfaces, buffering of input and output

lines, and implementing isolated line receivers in

high noise environments.
