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, sole-
noids, 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 appli-
cations requiring additional drive lines. Similar devices with reduced
r
DS(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擄C.
