General Description

The VHCT245A is an advanced high speed CMOS octal bus transceiver fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHCT245A is intended for bidirectional asynchronous communication between data busses. The direction of data transmission is determined by the level of the T/R input. The enable input can be used to disable the device so that the busses are effectively isolated.

Features

■ High Speed: tPD = 5.4ns (Typ.) at VCC = 5V

■ Power Down Protection on Inputs and Outputs

■ Low Power Dissipation: ICC = 4µA (Max.) @ TA = 25°C

■ Pin and Function Compatible with 74HCT245

74VHCT245A属于集成电路（IC） > 缓冲器，驱动器，接收器，收发器。安森美半导体公司制造生产的74VHCT245A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。
