Description
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.
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
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.

• Microprocessor System
Interfaces
A 0.1 µF bypass capacitor must be connected between pins 5 and 8.
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.

The Electrical and Switching
Characteristics of the HCPL2200/2219 are guaranteed over
the temperature range of 0°C to
85°C and a VCC range of 4.5 volts
to 20 volts. Low IF and wide VCC
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.

*The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous
voltage rating. For the continuous voltage rating refer to the VDE 0884 Insulation Characteristics Table (if applicable), your equipment level
safety specification or HP Application Note 1074 entitled “Optocoupler Input-Output Endurance Voltage,” publication number 5963-2203E.

Notes:
1. Derate total package power dissipation, PT, linearly above 70°C free air
temperature at a rate of 4.5 mW/°C.
2. Duration of output short circuit time
should not exceed 10 ms.
3. Device considered a two-terminal
device: pins 1, 2, 3, and 4 shorted
together and pins 5, 6, 7, and 8
shorted together.
4. The tPLH propagation delay is
measured from the 50% point on the
leading edge of the input pulse to the
1.3 V point on the leading edge of the
output pulse. The tPHL propagation
delay is measured from the 50% point
on the trailing edge of the input pulse
to the 1.3 V point on the trailing edge
of the output pulse.
5. When the peaking capacitor is omitted,
propagation delay times may increase
by 100 ns.
6. CML is the maximum rate of rise of the
common mode voltage that can be
sustained with the output voltage in the
logic low state (VO < 0.8 V). CMH is
the maximum rate of fall of the
common mode voltage that can be

recommended.
8. In accordance with UL1577, each
optocoupler is proof tested by applying
an insulation test voltage ≥ 3000 V rms
for one second (leakage detection
current limit, II-O ≤ 5 µA). This test is
performed before the 100% production
