Overview
6595 ADVANCE INFORMATION (Subject to change without notice) January 24, 2000 POWER GROUND LOGIC SUPPLY SERIAL DATA IN OUT 0 OUT 1 OUT 2 OUT 3 REGISTER CLEAR OUTPUT ENABLE POWER GROUND POWER GROUND LOGIC GROUND SERIAL DATA OUT OUT 7 OUT 6 OUT 5 OUT 4 CLOCK STROBE POWER GROUND 8-BIT SERIAL-INPUT, DMOS POWER DRIVER The A6595KA and A6595KLW combine 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 A6A595.
The A6595 DMOS open-drain outputs are capable of sinking up to 750 mA.
All of the output drivers are disabled (the DMOS sink drivers turned off) by the OUTPUT ENABLE input high.
The A6595KA is furnished in a 20-pin dual in-line plastic package.
The A6595KLW is furnished in a wide-body, small-outline plastic package (SOIC) with gull-wing leads.
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.
