MC74LCX138, Low-Voltage CMOS 3-to-8 Decoder/Demultiplexer

DATA SHEET www.onsemi.com Low-Voltage CMOS 3-to-8 Decoder/Demultiplexer With 5 V Tolerant Inputs MC74LCX138 The MC74LCX138 is a high performance, 3 to 8 decoder/demultiplexer operating from a 1.65 to 5.5 V supply.

High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance.

A VI specification of 5.5 V allows MC74LCX138 inputs to be safely driven from 5 V devices.

MC74LCX138 Features

* three Enable inputs, two active-LOW (E1, E2) and one active-HIGH (E3). All outputs will be HIGH unless E1 and E2 are LOW, and E3 is HIGH. This multiple enabled function allows easy parallel expansion of the device to a 1
