Description

This HCNW138 high gain series coupler uses a Light Emitting Diode and an integrated high gain photodetector to provide extremely high current transfer ratio between input and output. Separate pins for the photodiode and output stage result in TTL compatible saturation voltages and high speed operation. Where desired VCC and VO terminals may be tied together to achieve convention photodarlington operation.A base access terminal allows a gain bandwidth adjustment to be made.

The HCNW138 is designed for use mainly in TTL applications. Current transfer ratio (CTR) is 300% minimum over 0 to 70 degrees C for an LED current of 1.6 mA (1 TTL Unit load). A 300% minimum CTR enables operation with 1 TTL Load using a 2.2 k ohm pull-up resistor.Selection for lower input current down to 250 mA is available upon request.

The HCNW138 is packaged in a widebody encapsulation that provides creepage and clearance dimensions suitable for safety approval by regulatory agencies worldwide.
