ADVANCE INFORMATION
8-BIT LATCHED
DMOS POWER DRIVER
(Subject to change without notice)
January 24, 2000
The A6273KA and A6273KLW combine eight (positive-edge-
triggered D-type) data latches and DMOS outputs for systems requiring
relatively high load power. Driver applications include relays, sole-
noids, and other medium-current or high-voltage peripheral power loads.
The CMOS inputs and latches allow direct interfacing with microproces-
sor-based systems. Use with TTL may require appropriate pull-up
resistors to ensure an input logic high.

The DMOS output inverts the DATA input. All of the output
drivers are disabled (the DMOS sink drivers turned OFF) with the
CLEAR input low. The A6273KA/KLW DMOS open-drain outputs are
capable of sinking up to 750 mA. Similar devices with reduced rDS(on)
will be available as the A6A273.

The A6273KA is furnished in a 20-pin dual in-line plastic package.
The A6273KLW is furnished in a 20-lead wide-body, small-outline
plastic package (SOIC) with gull-wing leads for surface-mount applica-
tions. 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.

Note that the A6273KA (DIP) and the A6273KLW
(SOIC) are electrically identical and share a com-
mon terminal number assignment.
