General

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.

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

500mA, limited only by package power dissipation.

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.

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.
