三态输出八组总线收发器

TM74HC138是一款高速COMS器件，引脚兼容低功耗肖基特TTL（LSTTL）系列。TM74HC138有三个地址数据输入端（A0、A1、A2）和八个有效译码为低的输出端（Y0 - Y7）；TM74HC138有三个使能控制端（E1 、E2 、E 3），当E1 、E2为低电平且E3为高电平时，八个译码输出端才有译码输出，否则八个译码输出端将全为高。TM74HC138通常应用于单个三地址数据输入八译码输出的3-8译码器，也可根据使能信号特点用两个TM74HC138实现四地址数据输入和16 译码输出的 4-16 译码器，应用中未使用的使能端要处在译码有效输出使能电平状态。 • 采用 CMOS工艺\n• 低功耗\n• 响应速度快\n• 工作电压范围：3.0V--5.5Ｖ\n• 适用领域：消费类电子产品，适用于数字电路中的3—8译码功能\n• 封装形式：SOP16、DIP16、QFN16(3*3);

1-of-8 Decoder/Demultiplexer

The MC74HC138A is identical in pinout to the LS138. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC138A decodes a three−bit Address to one−of−eight active−low outputs. This device features three Chip Select inputs,
