The 74HCT138D,652 IC has the following pin configuration:
The 74HCT138D,652 operates based on the principle of binary decoding. The three address inputs (A0, A1, A2) represent a 3-bit binary code, which is decoded to activate one of the eight output lines (Y0-Y7). The active LOW enable input (/G1) controls the operation of the decoder/demultiplexer.
When /G1 is HIGH, all outputs are in a high-impedance state. When /G1 is LOW, the selected output line corresponding to the binary input code becomes active (LOW), while the remaining output lines remain inactive (HIGH).
The 74HCT138D,652 finds application in various digital systems where decoding and demultiplexing functions are required. Some common application fields include:
Some alternative models that provide similar functionality to the 74HCT138D,652 include:
