74HC165PW-Q100屬于集成電路（IC）的移位寄存器。由安世半導體(中國)有限公司制造生產的74HC165PW-Q100移位寄存器移位寄存器是低級邏輯器件，通常用于在串行和并行方式之間轉換數(shù)字邏輯信號形式的數(shù)據(jù)，或在數(shù)字字內移動數(shù)據(jù)位的位置。移位寄存器通常使用集成到一個設備中的一組觸發(fā)器來實現(xiàn)，常用于集成度更高的邏輯器件，但仍可用于 I/O 擴展等應用，在這些應用中離散形式的函數(shù)可能會非常有用。

1. General description

The 74HC165-Q100; 74HCT165-Q100 are 8-bit serial or parallel-in/serial-out shift registers.

The device features a serial data input (DS), eight parallel data inputs (D0 to D7) and two

complementary serial outputs (Q7 and Q7). When the parallel load input (PL) is LOW the data from

D0 to D7 is loaded into the shift register asynchronously. When PL is HIGH data enters the register

serially at DS. When the clock enable input (CE) is LOW data is shifted on the LOW-to-HIGH

transitions of the CP input. A HIGH on CE will disable the CP input. Inputs are overvoltage tolerant

to 15 V. This enables the device to be used in HIGH-to-LOW level shifting applications.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
