Data Sheet
26186.122
6B259
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 mediumcurrent or high-voltage peripheral power loads.
The CMOS inputs and latches allow direct interfacing with microprocessor-based systems. Use with TTL may require appropriate pullup 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 available 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 surfacemount 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.
FEATURES
■ 50 V Minimum Output Clamp Voltage
■ 150 mA Output Current (all outputs simultaneously)
■ 5 Ω Typical rDS(on)
■ Low Power Consumption
■ Replacements for TPIC6B259N and TPIC6B259DW

FUNCTIONAL DESCRIPTION and INPUT REQUIREMENTS
Four modes of operation are selectable by controlling
the CLEAR and ENABLE inputs as shown above.
ENABLE
DATA
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.

OUTPUT SWITCHING TIME
ENABLE
In the demultiplexing/decoding mode, the addressed
output inverts the data input and all other outputs are OFF.
50%
t h(D)
t su(D)
DATA
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 clear mode, all outputs are OFF and are unaffected by the DATA or address (SN) inputs.

DATA INPUT REQUIREMENTS
Data Active Time Before Enable
(Data Set-Up Time), tsu(D) .............................................. 20 ns
Data Active Time After Enable
(Data Hold Time), th(D) ................................................... 20 ns
Data Pulse Width, tw(D) ....................................................... 40 ns
Input Logic High, VIH ................................................ ≥ 0.85VCC
Input Logic Low, VIL ................................................. ≤ 0.15VCC

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.
