FST32211G数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

General Description
The Fairchild Switch FST32211 provides up to 48-bits of high-speed CMOS TTL-compatible bus switching. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.
The device can be organized as four 12-bit, two 24-bit, or one 48-bit bus switch. When routed as a 40-bit bus switch, the device can be organized as four 10-bit, two 20-bit or one 40-bit bus switch. When OE1 is LOW, the switch is ON and Port 1A is connected to Port 1B. When OE2 is LOW, the switch is ON and Port 2A is connected to Port 2B. When OE3 is LOW, the switch is ON and Port 3A is connected to Port 3B. When OE4 is LOW, the switch is ON and Port 4A is connected to Port 4B. When OE1, OE2, OE3, or OE4 are HIGH, a high impedance state exists between the A and B Ports.

特性 Features

■ 4Ω switch connection between two ports
■ Minimal propagation delay through the switch
■ Low lCC
■ Zero bounce in flow-through mode
■ Control inputs compatible with TTL level
■ Packaged in plastic Fine Pitch Ball Grid Array (FBGA) 

简介

FST32211G属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的FST32211G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。
