Product details

Dual 4:1 multiplexer for 5V logic routing

The Texas Instruments SN74F253D is a dual 4:1 multiplexer from the 74F series, packing two independent 4-input to 1-output selector circuits into a single 16-SOIC package. It selects one of four data sources per mux based on a common select bus and individual output-enable controls. Typical applications include data routing, bus-oriented multiplexing, and signal selection in 5V logic systems such as telecom line cards, industrial control panels, and test equipment where board space is tight.

What the 2 x 4:1 circuit means for your BOM

Two 4:1 muxes in one package route eight data lines to two outputs using a shared three-bit address. Output drive is 3 mA high, 24 mA low.

Supply and temperature — commercial-grade 5V logic

Operates on a single 4.5 V to 5.5 V supply. Temperature range is 0 °C to 70 °C.

Lifecycle and sourcing

The SN74F253D is listed as Active with ROHS3 compliance.

Frequently asked questions

Is SN74F253D the same as 74F253D?

The SN74F253D is Texas Instruments' specific ordering code for the 74F253 function in a 16-SOIC package. The base function 74F253 is a standard logic type, but the full SN74F253D part number includes the manufacturer prefix and package suffix. Always use the full MPN for procurement.

What is the SN74F253D used for?

It is a dual 4:1 multiplexer used for data routing, bus selection, and signal multiplexing in 5V digital systems. It replaces two separate 4:1 muxes or a larger mux where board space is limited.

Does the SN74F253D require external pull-up resistors?

No. The outputs are totem-pole (push-pull) with active drive both high and low — 3 mA source, 24 mA sink. No pull-up resistors are needed on the outputs.
