The TC74VHC139 is an advanced high speed CMOS 2 to 4

LINE DECODER/DEMULTIPLEXER fabricated with silicon

gate C2MOS technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

The active low enable input can be used for gating or it can be

used as a data input for demultiplexing applications.

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 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

•

High speed: t = 5.0 ns (typ.) at V

= 5 V

Low power dissipation: I

= 4 μA (max) at Ta = 25°C

High noise immunity: V

= V

= 28% V

NIH

NIL CC (min)

Power down protection is provided on all inputs.

Balanced propagation delays: t ≈ t

pLH

pHL

Wide operating voltage range: V

= 2 V to 5.5 V

CC (opr)

Pin and function compatible with 74ALS139
