Product details

The Texas Instruments SN74HC158DT is a 74HC-series CMOS multiplexer with a 4 x 2:1 circuit in a 16-SOIC surface-mount package. It operates from 2V to 6V supply and -40°C to 85°C temperature range.

Ratings that decide the fit

The 4 x 2:1 circuit routes four bits at once. Supply range is 2V to 6V. Output drive is 7.8 mA per pin. Package is 16-SOIC.

TI keeps the 74HC family running for industrial and legacy-support customers.

Frequently asked questions

What is the function of SN74HC158DT?

It is a 4-channel, 2-input to 1-output CMOS multiplexer. It selects one of two 4-bit data buses and routes the chosen nibble to the outputs, controlled by a single select line and an active-low output enable.

Is SN74HC158DT compatible with 5V logic?

Yes. The supply range is 2V to 6V, so it operates directly on a 5V rail. Input and output levels are compatible with standard 5V CMOS and TTL logic families at that supply voltage.
