Description
The A6B595 combines an 8-bit CMOS shift register and accompanying data latches, control circuitry, and DMOS power driver outputs. Power driver applications include relays, solenoids, and other medium-current or high-voltage peripheral power loads.
The serial-data input, CMOS shift register and latches allow direct interfacing with microprocessor-based systems. Serial data input rates are over 5 MHz. Use with TTL may require appropriate pull-up resistors to ensure an input logic high.
A CMOS serial-data output enables cascade connections in applications requiring additional drive lines. Similar devices with reduced rDS(on) are available as the A6595.
The A6B595 DMOS open-drain outputs are capable of sinking up to 500 mA. All of the output drivers are disabled (the DMOS sink drivers turned off) by the OUTPUT ENABLE input high. 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 85°C.
The A6B595 is furnished in a 20-pin dual in-line plastic package and a 20-pin wide-body, small-outline plastic package (SOICW) with gull-wing leads. The Pb (lead) free versions (suffix -T) have 100% matte tin leadframe plating.
