MC14556B Dual Binary to 1-of-4 Decoder/Demultiplexer

DATA SHEET www.onsemi.com Dual Binary to 1-of-4 Decoder/Demultiplexer MC14555B, MC14556B 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 .
