8-BIT SERIAL-INPUT,

DMOS POWER DRIVER

The A6595KA and A6595KLW combine an 8-bit CMOS shift

register and accompanying data latches, control circuitry, and DMOS

power driver outputs. Power driver applications include relays, sole-

noids, and other medium-current or high-voltage peripheral power

loads.

The serial-data input, CMOS shift register and latches allow direct

interfacing with microprocessor-based systems. Serial-data input rates

are over 5 MHz. Use with TTL may require appropriate pull-up

resistors to ensure an input logic high.

A CMOS serial-data output enables cascade connections in appli-

cations requiring additional drive lines. Similar devices with reduced

The A6595 DMOS open-drain outputs are capable of sinking up to

750 mA. All of the output drivers are disabled (the DMOS sink drivers

turned off) by the OUTPUT ENABLE input high.

The A6595KA is furnished in a 20-pin dual in-line plastic package.

The A6595KLW is furnished in a wide-body, small-outline plastic

package (SOIC) with gull-wing leads. Copper lead frames, reduced

supply current requirements, and low on-state resistance allow both

devices to sink 150 mA from all outputs continuously, to ambient

temperatures over 85

°C.
