MC74LCX139
Dual Low−Voltage CMOS
2−to−4 Decoder/Demultiplexer
With 5V−Tolerant Inputs
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
to be safely driven from 5 V devices. The MC74LCX139 is suitable
for memory address decoding and other TTL level bus oriented
applications.
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.
