Functional Block Diagram
8-Bit Serial-Input DMOS Power Driver
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 r
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.
DS(on)
are available as the A6595.
