Product details

What this quad 2:1 mux is and where it fits

The CY74FCT157CTD is a 4 x 2:1 multiplexer from the 74FCT logic family, packaged in a 16-pin SOIC for surface-mount assembly. It selects one of two 4-bit data sources onto a common output bus, controlled by a single select line. The independent circuit count of 1 means all four mux sections share the same select and enable — you get one quad mux, not four standalone switches. Operates on a single 4.75 V to 5.25 V supply. Temperature range is -40°C to 85°C. Output drive is 32 mA high, 64 mA low.

Sourcing and lifecycle — no obsolescence to chase

This part is listed as Active in production, with ROHS3 compliance. No last-time-buy notice, no phase-out pressure.

Frequently asked questions

Can CY74FCT157CTD replace a 74FCT157?

Yes — CY74FCT157CTD is the exact 74FCT157 function in a surface-mount 16-SOIC package. If your BOM calls for a 74FCT157 in a DIP or other package, check the footprint; the logic is identical.
