SN74LV165ADRE4 by Texas Instruments

The SN74LV165ADRE4 is a high-performance, 8-bit parallel-load shift register designed by Texas Instruments, which is renowned for its innovation in semiconductor technology. This integrated circuit (IC) is part of the 'LV' family, which stands for 'low-voltage'. It operates effectively in a wide range of applications that require the serial unloading of parallel data.

Constructed with advanced silicon-gate CMOS technology, the SN74LV165ADRE4 offers optimal power and speed characteristics while maintaining the low power consumption that is crucial for battery-powered and energy-efficient designs. The device is capable of functioning over a broad voltage range of 2V to 5.5V, which provides a great deal of flexibility for various system voltages, making it suitable for interfacing with both 3.3V and 5V systems.

Featuring a direct overriding clear (SRCLR) input and a clock (CP) input, the SN74LV165ADRE4 allows for parallel data to be loaded into the register using the parallel input lines (A to H) when the shift/load (SH/LD) input is held low. Upon shifting to a high state, the SH/LD input enables the serial output of data on the QH' output pin with each pulse of the CP clock input. This makes the device exceptionally useful for converting parallel data to serial form, which is often required when interfacing with microcontrollers, data acquisition systems, or during the expansion of I/O ports.

The SN74LV165ADRE4 comes in a compact surface-mount package, specifically the TSSOP (Thin Shrink Small Outline Package) with 16 pins, designated by the 'DRE4' suffix in its product name. This package is well-suited for space-constrained applications, and its small size does not compromise its performance or reliability.

In summary, the SN74LV165ADRE4 is a versatile and reliable component for digital systems requiring the conversion of parallel data to serial format. Its low-power operation, wide voltage range compatibility, and compact form factor make it an excellent choice for a variety of electronic designs.
