MM74C154
4-Line to 16-Line Decoder/Demultiplexer
General Description
The MM74C154 one of sixteen decoder is a monolithic
complementary MOS (CMOS) integrated circuit con-
structed with N- and P-channel enhancement transistors.
The device is provided with two strobe inputs, both of
which must be in the logical "0" state for normal operation.
If either strobe input is in the logical "1" state, all 16 outputs
will go to the logical "1" state.
To use the product as a demultiplexer, one of the strobe
inputs serves as a data input terminal, while the other
strobe input must be maintained in the logical "0" state. The
information will then be transmitted to the selected output
as determined by the 4-line input address.

Absolute Maximum Ratings
(Note 1)
Note 1: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed. Except for "Operating Tempera-
ture Range" they are not meant to imply that the devices should be oper-
ated at these limits. The table of "Electrical Characteristics" provides
conditions for actual device operation.
