ADVANCE INFORMATION
8-BIT ADDRESSABLE
DMOS POWER DRIVER
(Subject to change without notice)
March 22, 2000
The A6A259KA and A6A259KLB combine a 3-to-8 line CMOS
decoder and accompanying data latches, control circuitry, and DMOS
outputs in a multi-functional power driver capable of storing single-line
data in the addressable latches or use as a decoder or demuliplexer.
Driver applications include relays, solenoids, and other medium-current
or high-voltage peripheral power loads.

The CMOS inputs and latches allow direct interfacing with micro-
processor-based systems. Use with TTL may require appropriate pull-
up resistors to ensure an input logic high. Four modes of operation are
selectable with the CLEAR and ENABLE inputs.

The addressed DMOS output inverts the DATA input with all
unaddressed outputs remaining in their previous states. All of the output
drivers are disabled (the DMOS sink drivers turned off) with the
CLEAR input low and the ENABLE input high. The A6A259KA/KLB
DMOS open-drain outputs are capable of sinking up to 500 mA.

The A6A259KA is furnished in a 20-pin dual in-line plastic pack-
age. The A6A259KLB is furnished in a 24-lead wide-body, small-
outline plastic batwing package (SOIC) with gull-wing leads for surface-
mount applications. Copper lead frames, reduced supply current re-
quirements, and low on-state resistance allow both devices to sink 150
mA from all outputs continuously, to ambient temperatures over 85°C.
