MC14555B MC14556B
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–hexade-
cimal (1–of–16), etc., can be achieved by using other MC14555B or
MC14556B devices.
Applications include code conversion, address decoding, memory selec-
tion control, and demultiplexing (using the Enable input as a data input) in
digital data transmission systems.

This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, pre-
cautions must be taken to avoid applications of
any voltage higher than maximum rated volt-
ages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.
