SN74HC151D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

SN74HC151D属于集成电路（IC）的信号开关多路复用器解码器。由德州仪器制造生产的SN74HC151D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。

1 Features

• Wide operating voltage range of 2 V to 6 V

• Outputs can drive up to 10 LSTTL loads

• Low power consumption, 80-μA max ICC

• Typical tpd = 13 ns

• ±6-mA Output drive at 5 V

• Low input current of 1 μA max

• 8-Line to 1-line multiplexers can perform as:

– Boolean-function generators

– Parallel-to-serial converters

– Data source selectors

2 Description

This data selector/multiplexer provides full binary

decoding to select one of eight data sources. The

strobe (G) input must be at a low logic level to enable

the inputs. A high level at the strobe terminal forces

the standard output (Y) low and the inverted output

(W) high.
