ADVANCE INFORMATION
(Subject to change without notice)
January 24, 2000
8-BIT ADDRESSABLE
DMOS POWER DRIVER
The A6B259KA and A6B259KLW 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 A6B259KA/KLW DMOS open-drain outputs are capable of
sinking up to 500 mA. Similar devices with reduced r
DS(on)
are avail-
able as the A6259KA/KLW.
The A6B259KA is furnished in a 20-pin dual in-line plastic
package. The A6B259KLW 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 either device to sink
150 mA from all outputs continuously, to ambient temperatures greater
than 85擄C.
