74AHC139; 74AHCT139
Dual 2-to-4 line decoder/demultiplexer
The 74AHC139; 74AHCT139 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 are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.
Features and benefits
Wide supply voltage range from 2.0 to 5.5 V
Balanced propagation delays
All inputs have Schmitt-trigger actions
High noise immunity
Overvoltage tolerant inputs to 5.5 V
Input levels:
For 74AHC139: CMOS level
For 74AHCT139: TTL level
