MC74LCX139
Dual LowVoltage CMOS
2to4 Decoder/Demultiplexer
With 5VTolerant Inputs
The MC74LCX139 is a high performance, 2to4 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
I
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 highspeed 2to4 decoder/demultiplexer
accepts two binary weighted inputs (A0, A1) and, when enabled,
provides four mutually exclusive activeLOW 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 8output demultiplexer by
using one of the activeLOW 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.
Current drive capability is 24 mA at the outputs.
