MIC5891

General Description

The MIC5891 latched driver is a high-voltage, high current

integrated circuit comprised of eight CMOS data latches,

CMOS control circuitry for the common STROBE and OUT-

PUT ENABLE, and bipolar Darlington transistor drivers for

each latch.

Bipolar/MOS construction provides extremely low power

latches with maximum interface ﬂexibility.

The MIC5891 will typically operate at 5MHz with a 5V logic

supply.

The CMOS inputs are compatible with standard CMOS,

PMOS, and NMOS logic levels. TTL circuits may be used

with appropriate pull-up resistors to ensure a proper logic-

high input.

A CMOS serial data output allows additional drivers to be

cascaded when more than 8 bits are required.

The MIC5891 has open-emitter outputs with suppression

diodes for protection against inductive load transients. The

output transistors are capable of sourcing 500mA and will

sustain at least 35V in the on-state.

Simultaneous operation of all drivers at maximum rated

current requires a reduction in duty cycle due to package

power limitations. Outputs may be paralleled for higher load

current capability.

The MIC5891 is available in a 16-pin plastic DIP package

(N) and 16-pin wide SOIC package (WM).
