74LV165PW-Q100J

Introduction

74LV165PW-Q100J is a family of shift registers made by Texas Instruments. It belongs to the Logic - Shift Registers category. This device provides 8-bit parallel-load and serial-in/serial-out (shift-register) functions. It is ideal for applications, where a large number of digital devices all require the same information. 74LV165PW-Q100J requires only three control signals for operation, which are the "shift in" (SI), "shift out"(SO) and "parallel-load"(PL).

Application Field

The 74LV165PW-Q100J is widely used in different areas, such as in biometrics, medical imaging and displays control. For example, in biometrics, the chip can be used to control the identity verification process. It can also be used in medical imaging field, such as CT scans, MRI, and ultrasonic. In addition, the 74LV165PW-Q100J can be used to control the display signals on LCD and OLED displays, such as in the displays of TV, computer and mobile phones.

Working Principle

The working principle of the 74LV165PW-Q100J is quite simple. The circuit diagram of the register is shown in Figure 1. When SI is set to “low”, the information present at the first input pin is shifted out of the register and the content of the first input pin is shifted to the next input pin. This data shifting process continues until the information is shifted out of all 8-bit registers. When the PL is set to “low”, all 8-bits of data in the register will be loaded simultaneously. The 75LV165PW-Q100J can also be cascaded in different ways. That is, the output of one register can be connected to the input of another register. This way, the data can be shifted out or loaded into multiple registers in one operation.
