ADVANCE INFORMATION
8-BIT LATCHED
DMOS POWER DRIVER
(Subject to change without notice)
January 24, 2000
The A6B273KA and A6B273KLW 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
microprocessor-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 A6B273KA/KLW DMOS open-drain outputs
are capable of sinking up to 500 mA. Similar devices with reduced

package. The A6B273KLW is furnished in a 20-lead wide-body,
small-outline plastic package (SOIC) with gull-wing leads for surface-
mount applications. 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 A6B273KA (DIP) and the A6B273KLW
(SOIC) are electrically identical and share a common
terminal number assignment.

protection (Class 3) but are still susceptible to damage if
exposed to extremely high static electrical charges.
