MC74LCX139, Dual Low Voltage CMOS 2-to-4 Decoder/Demultiplexer

MC74LCX139 Dual Low-Voltage CMOS 2-to-4 Decoder/Demultiplexer With 5 V Tolerant Inputs The MC74LCX139 is a high performance, 2 to 4 decoder/ demultiplexer operating from a 2.3 to 3.6 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 MC74LCX139 inputs to be safely driven from 5 V devices.

The MC74LCX139 is suitable

MC74LCX139 Features

* an active low Enable input. All outputs will be HIGH unless En is LOW. The LCX139 can be used as an 8

* output demultiplexer by using one of the active

* LOW Enable inputs as the data input and the other Enable input as a strobe. The Enable inputs which are not used must be permanently t
