ADVANCE INFORMATION
8-BIT SERIAL-INPUT,
DMOS POWER DRIVER
(Subject to change without notice)
January 24, 2000
The A6B595KA and A6B595KLW 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.

The A6B595 DMOS open-drain outputs are capable of sinking up
to 500 mA. All of the output drivers are disabled (the DMOS sink
drivers turned off) by the OUTPUT ENABLE input high.

Note that the A6B595KA (DIP) and the
A6B595KLW (SOIC) are electrically identical and
share a common terminal number assignment.
The A6B595KA is furnished in a 20-pin dual in-line plastic
package. The A6B595KLW 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.
