8-BIT ADDRESSABLE DMOS POWER DRIVER
The A6259KA and A6259KLW 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 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 addressed DMOS output inverts the DATA input with all unaddressed outputs remaining in their previous states. All of the output drivers are disabled (the DMOS sink drivers turned off) with the CLEAR input low and the ENABLE input high. The A6259KA/KLW DMOS open-drain outputs are capable of sinking up to 750 mA. Similar devices with reduced rDS(on) are available as the A6A259. The A6259KA is furnished in a 20-pin dual in-line plastic package. The A6259KLW 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 85C.

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
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 unaffected by the DATA or address (SN) inputs.
