Motorola Small–Signal Transistors, FETs and Diodes Device Data
•Optimized to Switch 3 V to 5 V Relays from a 5 V Rail
•Compatible with “TX’’ and “TQ’’ Series Telecom Relays Rated up to
625 mW at 3 V to 5 V
•Features Low Input Drive Current
•Internal Zener Clamp Routes Induced Current to Ground Rather Than
Back to Supply
•Guaranteed Off State with No Input Connection
•Supports Large Systems with Minimal Off–State Leakage
•ESD Resistant in Accordance with the 2000 V Human Body Model
•Provides a Robust Driver Interface Between Relay Coil and Sensitive
Logic Circuits
Applications include:
•Telecom Line Cards and Telephony
•Industrial Controls
•Security Systems
•Appliances and White Goods
•Automated Test Equipment
•Automotive Controls
This device is intended to replace an array of three to six discrete
components with an integrated part. It can be used to switch other 3 to 5
Vdc Inductive Loads such as solenoids and small DC motors.
