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.","metaTitle":"CY74FCT157CTD 74FCT Multiplexer, 4x2:1, 16-SOIC, -40 to 85°C","metaDescription":"CY74FCT157CTD is a 4 x 2:1 multiplexer from the 74FCT series.
