MC74LCX139

Dual Low−Voltage CMOS

2−to−4 Decoder/Demultiplexer

With 5V−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 V specification of 5.5 V allows MC74LCX139 inputs

to be safely driven from 5 V devices. The MC74LCX139 is suitable

for memory address decoding and other TTL level bus oriented

applications.

The MC74LCX139 high−speed 2−to−4 decoder/demultiplexer

accepts two binary weighted inputs (A0, A1) and, when enabled,

provides four mutually exclusive active−LOW outputs. The LCX139

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 tied to ground.
