74VHC139 decoder/demultiplexer equivalent, dual 2-to-4 decoder/demultiplexer.
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 pro.
When the enable input is held HIGH, all four outputs are fixed at a HIGH logic level independent of the other inputs. A.
The VHC139 is an advanced high speed CMOS Dual 2-to4 Decoder/Demultiplexer fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation..
