CD74AC157中文资料四路 2 输入同向乘法器数据手册TI规格书

描述 Description

These quadruple 2-line to 1-line data selectors/multiplexers are designed for 1.5-V to 5.5-V VCC operation.
The ’AC157 devices feature a common strobe (G)\\ input. When the strobe is high, all outputs are low. When the strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The devices provide true data.

特性 Features

• AC Types Feature 1.5-V to 5.5-V Operation and Balanced Noise Immunity at 30% of the Supply Voltage
• Balanced Propagation Delays
• SCR-Latchup-Resistant CMOS Process and Circuit Design
• Exceeds 2-kV ESD Protection Per MIL-STD-883, Method 3015

简介

CD74AC157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CD74AC157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。
