Frequently Asked Questions

What is the primary function and key feature of the 74HC/HCT258?

It is a quad 2-input multiplexer with 3-state outputs, which selects four bits of data from two sources in an inverted form.

Is this device compatible with older TTL logic families?

Yes, the 74HC/HCT258 is high-speed Si-gate CMOS and is pin compatible with Low power Schottky TTL (LSTTL).

How does the data selection work using input S?

Source 0 data inputs are selected when 'S' is LOW, and Source 1 data inputs are selected when 'S' is HIGH.

What condition must the Output Enable (OE) pin meet to disable the outputs?

The output enable input (OE) is active LOW; removing the signal or raising it above a sufficient voltage forces the outputs into a high impedance OFF-state.
