Description

74HC138 . 3 TO 8 LINE DECODER DEMULTIPLEXER. Description. The 74HC138 is a high speed CMOS device. The device accepts a three bit binary weighted The MC74HC138A is identical in pinout to the LS138. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible SD-20070723- 74HC138 -V21. Page 1. Sungine. . CMOS 3-8 . . GC74HC138 CMOS The 74HC138 part in your lab kit has three rather interesting Enable inputs instead of demux is needed such as 1:4 16 or 1:5 32, two or four 74HC138 parts. The MC74HC165A is identical in pinout to the LS165. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible
