| MIC2981/2982 Micrel MIC2981/2982 High-Voltage High-Current Source Driver Array Preliminary Information 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 dualmarked device replaces either UDN2981 or UDN2982 devices. The MIC2981/82 is available in the 18-pin plastic DIP and 18lead wide SOP package. Both devices operate in the industrial temperature range.
