The Toshiba TC74VHC139FT is an advanced high-speed CMOS 2-to-4 line decoder/demultiplexer fabricated with silicon gate C2MOS technology. It achieves high-speed operation comparable to bipolar Schottky TTL while maintaining low CMOS power dissipation.
Key electrical characteristics include a typical propagation delay of 5.0 ns at 5V VCC and a low quiescent current of 4 μA maximum at 25°C. The device supports a wide operating voltage range from 2V to 5.5V, making it suitable for interfacing between 5V and 3V systems.
An active-low enable input can be used for gating or as a data input for demultiplexing. When the enable input is high, all four outputs are fixed at a high logic level, independent of other inputs. An input protection circuit allows 0 to 5.5V to be applied to input pins without regard to the supply voltage, preventing device destruction due to mismatched supply and input voltages.
The TC74VHC139FT is available in a SOP16 package, suitable for surface mount applications. Its pin and function are compatible with the 74ALS139.
The operating voltage range is 2 V to 5.5 V.
Typical propagation delay is 5.0 ns at VCC = 5 V.
Maximum quiescent current is 4 μA at Ta = 25°C.
It is available in a SOP16 surface mount package.
Storage temperature range is -65°C to 150°C.
The supply voltage range (absolute maximum) is -0.5 V to 7.0 V.
