HCPL-576X Datasheet, PDF (2/11 Pages) Agilent(Hewlett-Packard) – AC/DC to Logic Interface Hermetically Sealed Optocouplers

2
Each unit contains a light emit-
ting diode (LED), a threshold
sensing input buffer IC, and a
high gain photon detector to
provide an optocoupler which
permits adjustable external
threshold levels. The input buffer
circuit has a nominal turn on
threshold of 2.5 mA (I_TH+) and
3.6 volts (V ). The addition of
TH+
one or more external attenuation
resistors permits the use of this
device over a wide range of input
voltages and currents. Threshold
sensing prior to the LED and
detector elements minimizes
effects of any variation in optical
coupling. Hysteresis is also
provided in the buffer for extra
noise immunity and switching
stability.
The buffer circuit is designed
with internal clamping diodes to
protect the circuitry and LED
from a wide range of over-voltage
and over-current transients while
the diode bridge enables easy use
with ac voltage input.
These units combine several
unique functions in a single
package, providing the user with
an ideal component for computer

tions where a predetermined
input threshold optocoupler level
is desirable.
The high gain output stage
features an open collector output
providing both TTL compatible
saturation voltages and CMOS
compatible breakdown voltages.
This is an eight pin DIP which
may be purchased with a variety
of lead bend and plating options.
