4-Line to 16-Line Decoder/Demultiplexer
General Description
Each of these 4-line-to-16-line decoders utilizes TTL cir-
cuitry to decode four binary-coded inputs into one of six-
teen 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 out-
put 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 implementing high-performance memory decod-
ers. All inputs are buffered and input clamping diodes are
provided to minimize transmission-line effects and thereby
simplify system design.
