MIC2981/2982 Micrel, Inc. 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. These drivers can manage multiple loads of up to 50V and
500mA, limited only by package power dissipation. Output voltage to 50V
Output current to 500mA
Transient-protected outputs
Integral clamp diodes
TTL, CMOS, or PMOS compatible inputs 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. Ordering Information
