SY55854U中文资料Crosspoint Switches数据手册Microchip规格书

描述 Description

The SY55854U is a fully differential, CML, 2x2 crosspoint switch. The non-blocking design allows any input to be connected to any output. Varying the state of the select inputs allows SY55854U to be used in backup, fault tolerant, protection, and backplane distribution applications.SY55854U inputs can be terminated with a single resistor between the true and the complement pins of a given input.The SY55854U is a member of Micrel's new SuperLite™ family of high-speed logic devices. This family features very small packaging, high signal integrity, and flexible supply voltage operation.

简介

SY55854U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SY55854U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。
