The NLSF595 is advanced CMOS shift register with open drain outputs fabricated with 0.6 5m silicon gate CMOS technology. This device is used in conjunction with a microcontroller, with only one dedicated line. All pins have Overvoltage Protection that allows voltages above V
up to 7.0 V to be present on the pins without damage or disruption of operation of the part, regardless of the operating voltage. This device may be used between 2.0 and 5.5 volts, the output driver level may be independent of supply voltage:0-7.0 volts.

• Parallel Outputs are Open Drain Capable of Sinking > 12 mA Output Withstands up to +7.0 Regardless of V
