This small outline, low input current, high gain optocoupler is a single channel device in a five lead miniature footprint. Its SO-5 JEDEC registered (MO-155) package outline does not require "through holes" in a PCB. This package occupies approximately one-fourth the footprint area of the standard dual-in-line package. The lead profile is designed to be compatible with standard surface mount processes.
This high gain series optocoupler uses a Light Emitting Diode and an integrated high gain photodetector to provide extremely high current transfer ratio in between input and output. Separate pins for the photodiode and output stage results in TTL compatible saturation voltages and high speed operation. Where desired the VCC and VO terminals may be tied together to achieve conventional photodarlington operation.
It is designed for use mainly in TTL applications. Current Transfer Ratio is 300% minimum over 0 - 70 degrees C for an LED current of 1.6 mA [1 TTL Unit Load (U.L.)]. A 300% CTR enables operation with 1 U.L. out with a 2.2 k ohm pull-up resistor.
Selection for lower input currents down to 250 mA is available upon request.
