描述 Description

The MC74HCT595A consists of an 8 bit shift register and an 8 bit D-type latch with three state parallel outputs. The shift register accepts serial data and provides a serial output. The shift register also provides parallel data to the 8 bit latch. The shift register and latch have independent clock inputs. This device also has an asynchronous reset for the shift register. The HCT595A directly interfaces with the SPI serial data port on CMOS MPUs and MCUs. The device inputs are compatible with standard CMOS or LSTTL outputs.

簡介

MC74HCT595A屬于集成電路（IC）的移位寄存器。由制造生產(chǎn)的MC74HCT595A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(zhuǎn)換數(shù)字邏輯信號形式的數(shù)據(jù)，或在數(shù)字字內(nèi)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(shè)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(yīng)用，在這些應(yīng)用中離散形式的函數(shù)可能會非常有用。
