Features, Applications

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 to 500 mA. Similar devices with reduced rDS(on) are available as the A6259KA/KLW. The A6B259KA is furnished a 20-pin dual in-line plastic package. The A6B259KLW is furnished 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 85C.



Note that the A6B259KA (DIP) and the A6B259KLW (SOIC) are electrically identical and share a common terminal number assignment.
