MC74LVX245数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The MC74LVX245 is an advanced high speed CMOS octal bus transceiver. It is intended for two-way asynchronous communication between data buses. The direction of data transmission is determined by the level of the T/R input. The output enable pin (OE) can be used to disable the device, so that the buses are effectively isolated. All inputs are equipped with protection circuits against static discharge.

特性 Features

• High Speed: tPD = 4.7ns (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 APPLICATION NOTES 1. Do not force a signal on an I/O pin when it is an active output, damage may occur. 2. All floating (high impedence) input or I/O pins must be fixed by means of pull up or pull down r
• Pb-Free Packages are Available*

简介

MC74LVX245属于集成电路（IC）的缓冲器驱动器接收器收发器。由制造生产的MC74LVX245缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。
