MC14556BCP

到1 -的-4双二进制解码器/多路解复用器 Dual Binary to 1-of-4 Decoder/Demultiplexer

Dual Binary to 1−of−4 Decoder/Demultiplexer

The MC14555B and MC14556B are constructed with complementary MOS CMOS enhancement mode devices. Each Decoder/Demultiplexer has two select inputs A and B, an active low Enable input E, and four mutually exclusive outputs Q0, Q1, Q2, Q3. The MC14555B has the selected output go to the “high” state, and the MC14556B has the selected output go to the “low” state. Expanded decoding such as binary−to−hexadecimal 1−of−16, etc., can be achieved by using other MC14555B or MC14556B devices.
