描述 Description

High Performance Silicon Gate CMOS. The MC74HC597A is identical in pinout to the LS597. The device inputs are compatible with standard CMOS outputs, with pullup resistors,they are compatible with LSTTL outputs. This device consists of an 8 bit input latch which feeds parallel data to an 8 bit shift register. Data can also be loaded serially. The HC597A is similar in function to the HC589A, which is a 3 state device.

簡介

MC74HC597A屬于集成電路（IC）的移位寄存器。由制造生產(chǎn)的MC74HC597A移位寄存器移位寄存器是低級(jí)邏輯器件，通常用于在串行和并行方式之間轉(zhuǎn)換數(shù)字邏輯信號(hào)形式的數(shù)據(jù)，或在數(shù)字字內(nèi)移動(dòng)數(shù)據(jù)位的位置。移位寄存器通常使用集成到一個(gè)設(shè)備中的一組觸發(fā)器來實(shí)現(xiàn)，常用于集成度更高的邏輯器件，但仍可用于 I/O 擴(kuò)展等應(yīng)用，在這些應(yīng)用中離散形式的函數(shù)可能會(huì)非常有用。
