Caution: These CMOS devices have input static
protection (Class 3) but are still susceptible to
damage if exposed to extremely high static
electrical charges.
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, 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.
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, small-
outline 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 continu-
ously, to ambient temperatures over 85°C.
