Pin Definitions

Name

Pin Description

Enable input for both channels. Pull pin LOW to inhibit operation of the drivers. This input

has a precision threshold and comparator input stage.

5VB

IN1

IN2

5 V bypass pin for the internal 5 V regulator that provides power to the IC control circuitry.

Input to driver Channel 1. This input has TTL thresholds.

Input to driver Channel 2. This input has TTL thresholds.

Relay drive output 2: Open-drain output. HIGH impedance unless required active input(s)

are present and V_Sis above UVLO threshold.

OUT2

GND

Ground. Common ground reference for input and output circuits.

Relay drive output 1: Open-drain output. HIGH impedance unless required active input(s)

are present and V_Sis above UVLO threshold.

OUT1

Supply voltage. Provides power to the device. Usually connected to the bias voltage of the

relay being driven by the device.
