74HC139; 74HCT139
Dual 2-to-4 line decoder/demultiplexer
Rev. 4 — 11 December 2015
Product data sheet
1. General description
The 74HC139; 74HCT139 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 include clamp diodes. This enables the
use of current limiting resistors to interface inputs to voltages in excess of VCC.
2. Features and benefits
Input levels:
For 74HC139: CMOS level
For 74HCT139: TTL level
Demultiplexing capability
2 independent 2-to-4 decoders
