MC74HC240A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

High-Performance Silicon-Gate CMOS The MC74HC240A is identical in pinout to the LS240. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This octal noninverting buffer/line driver/line receiver is designed to be used with 3-state memory address drivers, clock drivers, and other sub-oriented systems. The device has inverting outputs and two active-low output enables. The HC240A is similar in function to the HC241A and HC244A.

特性 Features

• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 mA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard No. 7A
• Chip Complexity: 120 FETs or 30 Equivalent Gates
• Pb-Free Packages are Available*

简介

MC74HC240A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MC74HC240A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。
