Each unit contains a light emitting 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

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 input boards and other applications 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. See Selection

Guide Table for details. Standard Microcircuit Drawing

(SMD) parts are available for each lead style.
