SY100S863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

The SY100S863 is a PECL 8:1 multiplexer designed for use in new, high-performance PECL systems. It has differential PECL outputs and a standard TTL output. The TTL select inputs (SEL0, SEL1, SEL2) determine which one of the eight differential PECL data inputs (D0-D7) is propagated to the outputs. The enable pin, EN, is provided for expansion. When EN is at a TTL logic one level, both PECL and TTL outputs are enabled. When the enable pin is set to TTL logic zero level, both PECL outputs of the differential pair are in cut-off and the TTL output is in a three-state condition.

简介

SY100S863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SY100S863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。
