BU4028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

BU4028属于集成电路（IC）的信号开关多路复用器解码器。由罗姆半导体集团制造生产的BU4028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。

The BU4028B is a decoder which converts BCD signals to decimal signals.

Of the ten outputs Q0 to Q9, those corresponding to the A to D input codes are set to “H”, and the others are all set to “L”.

If inputs A to C are used and input D is used as disabled input, the BU4028B can also be used as a 1-of-8 decoder.

•Features

1) Low power dissipation.

2) Wide range of operating power supply voltages.

3) High input impedance.

4) High fan-out.

5) Direct drive of 2 L-TTL inputs and 1LS-TTL input.
