Overview
The NLSF595DTR2G, produced by ON Semiconductor, is an advanced CMOS shift register with open drain outputs. It is fabricated using 0.6 μm silicon gate CMOS technology. This device is designed to work in conjunction with a microcontroller, utilizing only one dedicated line. It features overvoltage protection, allowing voltages above VCC up to 7.0 V on the pins without causing damage or disrupting operation. The device operates within a voltage range of 2.0 to 5.5 volts, with output driver levels independent of the supply voltage up to 7.0 volts.
