74LVC139
Dual 2-to-4 line decoder/demultiplexer
Rev. 6 — 24 September 2021
Product data sheet
1. General description
The 74LVC139 decodes two binary weighted address inputs (nA0, nA1) to four mutually exclusive
outputs (nY0 to nY3). Each decoder features an enable input (nE). When nE is HIGH all outputs
are forced HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer
application. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of
these devices as translators in mixed 3.3 V and 5 V environments.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
