MC74LCX138, Low-Voltage CMOS 1-of-8 Decoder/Demultiplexer

www.DataSheet4U.com MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low-Voltage CMOS 1-of-8 Decoder/Demultiplexer With 5V-Tolerant Inputs MC74LCX138 The MC74LCX138 is a high performance, 1 of 8 decoder/ demultiplexer operating from a 2.7 to 3.6V 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 5.5V allows MC74LCX138 inputs to be safely driven

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

* of

* 32 (5 lines to 32 lines) decoder with just f
