74HC138PW-Q100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

74HC138PW-Q100属于集成电路（IC）的信号开关多路复用器解码器。由安世半导体(中国)有限公司制造生产的74HC138PW-Q100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. General description

The 74HC138-Q100; 74HCT138-Q100 decodes three binary weighted address inputs

(A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable

inputs (E1, E2 and E3). Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH.

This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder

with just four '138 ICs and one inverter. The '138 can be used as an eight output demultiplexer by

using one of the active LOW enable inputs as the data input and the remaining enable inputs as

strobes. Inputs include clamp diodes. This enables the use of current limiting resistors to interface

inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
