SN74CBT3345DWR集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

SN74CBT3345DWR属于集成电路（IC）的信号开关多路复用器解码器。由美国德州仪器公司制造生产的SN74CBT3345DWR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。

Standard ’245-Type Pinout

5-Ω Switch Connection Between Two Ports

TTL-Compatible Input Levels

description/ordering information

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.
