MIC2981/2982

High-Voltage High-Current Source Driver Array

General

Features

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 voltage to 50V

• Output current to 500mA

• Transient-protected outputs

• Integral clamp diodes

These drivers can manage multiple loads of up to 50V and

• TTL, CMOS, or PMOS compatible inputs

500mA, limited only by package power dissipation.

Applications

Micrel’s MIC2981/82 features inputs compatible with 5V TTL

and 5V to 15V CMOS or PMOS logic outputs. Micrel’s

dual-marked device replaces either UDN2981 or UDN2982

devices.

• Relay and solenoid switching

• Stepping motor

• LED and incandescent displays

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

18-lead wide SOP package. Both devices operate in the

industrial temperature range.
