Housed in a 16-SSOP package (0.154-inch body width, 3.90mm), it mounts on the board surface — the 0.025-inch pitch demands a standard fine-pitch soldering profile, nothing exotic for a rework station. ## Active production and supply status RoHS non-compliant per the manufacturer's classification — verify your assembly's exemption status before committing to a lead-free reflow profile. ## Temperature grade and deployment context It handles factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics where the board sees 70°C steady-state with 85°C spikes. The single-supply architecture (4.75V-5.25V) means it runs straight off a 5V rail without a secondary regulator — a clean fit for legacy TTL-logic buses or 5V-tolerant CMOS interfaces.","metaTitle":"CY74FCT2257CTQC Texas Instruments 4 x 2:1 Multiplexer","metaDescription":"Texas Instruments CY74FCT2257CTQC 4 x 2:1 multiplexer, 4.75V-5.25V supply, -40°C to 85°C temp range, 15mA/12mA output drive.
