4-Line to 16-Line Decoders Demultiplexers
General Description
Each or these 4-line-to-16-line decoders utilizes TTL circuit-
ry to decode four binary-coded inputs into one of sixteen
mutually exclusive outputs when both the strobe inputs G1
and G2 are low The demultiplexing function is performed
by using the 4 input lines to address the output line passing
data from one of the strobe inputs with the other strobe
input low When either strobe input is high all outputs are
high These demultiplexers are ideally suited for implement-
ing high-performance memory decoders All inputs are buff-
ered and input clamping diodes are provided to minimize
transmission-line effects and thereby simplify system de-
sign
