Caution: These CMOS devices have input static protection (Class 3) but are still susceptible to damage if exposed to extremely high static electrical charges. Data Sheet 26185.120 6595 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, 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 rDS(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°C.

On succeeding CLOCK pulses, the registers shift data information towards the SERIAL DATA OUTPUT. Information present at any register is transferred to the respective latch on the rising edge of the STROBE input pulse (serial-to-parallel conversion). When the OUTPUT ENABLE input is high, the output source drivers are disabled (OFF). The information stored in the latches is not affected by the OUTPUT ENABLE input. With the OUTPUT ENABLE input low, the outputs are controlled by the state of their respective latches. 6595 8-BIT SERIAL-INPUT, DMOS POWER DRIVER TEST CIRCUITS +15 V 0.11 Ω INPUT 100 mH tav IAS = 1.0 A IO DUT OUT VO V(BR)DSX VO(ON) Dwg.
