MM54C154 MM74C154 4-Line to 16-Line
Decoder Demultiplexer
General Description
The MM54C154 MM74C154 one of sixteen decoder is a
monolithic complementary MOS (CMOS) integrated circuit
constructed with N- and P-channel enhancement transis-
tors The device is provided with two strobe inputs both of
which must be in the logical 鈥樷€?鈥欌€?state for normal operation
If either strobe input is in the logical 鈥樷€?鈥欌€?state all 16 outputs
will go to the logical 鈥樷€?鈥欌€?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 鈥樷€?鈥欌€?state The infor-
mation will then be transmitted to the selected output as
determined by the 4-line input address
