Description
74VHC139 Dual 2-to-4 Decoder/Demultiplexer November 1992 Revised April 1999 74VHC139 Dual 2-to-4 Decoder/Demultiplexer General .
Features
* s High Speed: tPD = 5.0 ns (typ) at TA = 25°C s Low power dissipation: ICC = 4 µA (Max. ) at TA = 25°C s High noise immunity: VNIH = VNIL = 28% VCC (Min. ) s Power down protection is provided on all inputs s Pin and function compatible with 74HC139 Ordering Code: Order Number 74VHC139M 74VHC139SJ 74Applications
* When the enable input is held HIGH, all four outputs are fixed at a HIGH logic level independent of the other inputs. An input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply volt- age. This device can be used to interface 5V to 3V systems and74VHC139 Distributors
