DM74ALS373中文资料Octal D-Type 3-STATE Transparent Latch数据手册ONSEMI规格书

描述 Description

General Description
These 8-bit registers feature totem-pole 3-STATE outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. The high-impedance state and increased high-logic-level drive provide these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components. They are particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

特性 Features

■ Switching specifications at 50 pF
■ Switching specifications guaranteed over full temperature and VCC range
■ Advanced oxide-isolated, ion-implanted Schottky TTL process
■ Functionally and pin for pin compatible with LS TTL counterpart
■ Improved AC performance over DM74LS373 at approximately half the power
■ 3-STATE buffer-type outputs drive bus lines directly

简介

DM74ALS373属于集成电路（IC）的锁存器。由制造生产的DM74ALS373锁存器锁存器是类似于触发器的基本数字存储设备，但是不同之处在于，在锁存使能（或类似命名）信号处于有效逻辑状态的任何时间，保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态，而相反的是，状态仅在保持状态已固定时改变。
