MC74LVX573中文资料Octal D Latch 3-State Outputs数据手册ONSEMI规格书

描述 Description

The MC74LVX573 is an advanced high speed CMOS octal latch with 3-state outputs. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems. This 8-bit D-type latch is controlled by a latch enable input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state.

特性 Features

• High Speed: tPD = 6.4ns (Typ) at VCC = 3.3V
• Low Power Dissipation: ICC = 4µA (Max) at TA = 25 C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: VOLP = 0.8V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V PIN
• Pb-Free Packages are Available*

简介

MC74LVX573属于集成电路（IC）的锁存器。由制造生产的MC74LVX573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。
