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 microprocessor-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 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 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.
