A6A595KLB

6A595 ADVANCE INFORMATION (Subject to change without notice) March 22, 2000 8-BIT SERIAL-INPUT, DMOS POWER DRIVER The A6A595KA and A6A595KLB 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. The A6A595 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. The A6A595KA is furnished in a 20-pin dual in-line plastic package. The A6A595KLB is furnished in a 24-lead wide-body, smalloutline plastic batwing 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.
