Frequently Asked Questions

What is the primary function of the 74HC/HCT139?

It is a dual 2-to-4 line decoder/demultiplexer, providing two independent decoders.

How do I determine the dynamic power dissipation (PD)?

Use the formula: P = C × V × f + ∑ (C × V × f), where LCCo and CCi are capacitance values.

Is this device compatible with other logic levels?

Yes, it is high-speed Si-gate CMOS and is pin compatible with low power Schottky TTL.
