74HC139-Q100; 74HCT139-Q100 Dual 2-to-4 line decoder/demultiplexer Rev. 1 — 19 June 2014 Product data sheet 1. General description The 74HC139-Q100; 74HCT139-Q100 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 that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications. 2.
