exposed to extremely high static electrical charges.
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 rDS(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°C.

Four modes of operation are selectable by controlling
the CLEAR and ENABLE inputs as shown above.
In the addressable-latch mode, data at the DATA input
is written into the addressed transparent latch. The
addressed output inverts the data input with all other
outputs remaining in their previous states.
In the memory mode, all outputs remain in their
previous states and are unaffected by the DATA or
address (Sn) inputs. To prevent entering erroneus data in
the latches, ENABLE should be held HIGH while the
address lines are changing.
In the demultiplexing/decoding mode, the addressed
output inverts the data input and all other outputs are OFF.
In the clear mode, all outputs are OFF and are unaf-
fected by the DATA or address (SN) inputs.
Given the appropriate inputs, when DATA is LOW
for a given address, the output is OFF; when DATA is
HIGH, the output is ON and can sink current.
