6B259

6B259 ADVANCE INFORMATION (Subject to change without notice) January 24, 2000 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 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.
