4-Line to 16-Line DecodersDemultiplexers

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
