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°C to 85°C and a V
CC
range of 4.5 volts to
20 volts. Low I
F
and wide V
CC
range allow compatibility
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.
