SN74CBT3345中文资料5V、1:1 (SPST)、8 通道 FET 总线开关数据手册TI规格书

描述 Description

The SN74CBT3345 provides eight bits of high-speed TTL-compatible bus switching in a standard ’245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The device is organized as one 8-bit switch bank with dual output-enable (OE and OE)\\ inputs. When OE\\ is low or OE is high, the switch is on, and port A is connected to port B. When OE\\ is high and OE is low, the switch is open, and the high-impedance state exists between the two ports.

特性 Features

• Standard ’245-Type Pinout
• 5- Switch Connection Between Two Ports
• TTL-Compatible Input Levels

简介

SN74CBT3345属于集成电路（IC）的信号开关多路复用器解码器。由TI制造生产的SN74CBT3345信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
