MIC2981/82

High-Voltage, High-Current Source Driver Array

Features

General Description

• Output Voltage to 50V

The MIC2981/82 is an 8-channel, high-voltage,

high-current source driver array ideal for switching

high-power loads from logic-level TTL, CMOS, or

PMOS control signals.

• Output Current to 500 mA

• Transient-Protected Outputs

• Integral Clamp Diodes

These drivers can manage multiple loads of up to 50V

and 500 mA, limited only by package power

dissipation. The MIC2981/82 features inputs

compatible with 5V TTL and 5V to 15V CMOS or PMOS

logic outputs. Microchip’s dual-marked device replaces

either UDN2981 or UDN2982 devices.

• TTL, CMOS, or PMOS Compatible Inputs

Applications

• Relay and Solenoid Switching

• Stepping Motor

• LED and Incandescent Displays

The MIC2981/82 is available in the 18-lead plastic DIP

and 18-lead wide SOIC packages. Both devices

operate in the industrial temperature range.
