Description
The A6595 bines an 8-bit CMOS shift register and acpanying 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. Serialdata 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 A6595 DMOS open-drain outputs are capable of sinking up to 750 m A. All of the output drivers are disabled (the DMOS sink drivers turned off) by the OUTPUT ENABLE input high.
The A6595 is furnished in a 20-pin dual in-line plastic package that is lead (Pb) free, with 100% matte tin leadframe plating. Copper leadframe base material, reduced supply current requirements, and low on-state resistance allow the device to sink 150 m A from all outputs continuously, to ambient temperatures to 125°C.
