This is the through-hole 16-DIP variant, so it fits standard breadboards and solderable prototype boards without an adapter. Supply range is 4.5V to 5.5V, single-rail, making it a drop-in for classic 5V TTL or 5V CMOS logic systems. Output drive is specified at 3mA sourcing and 24mA sinking — enough to drive a LED through a resistor or feed the input of another 74F gate without a buffer. ## Temperature grade and package — bench to light industrial The 16-DIP (0.300-inch row spacing) package is through-hole, easy to hand-solder, and socket-friendly for prototyping. ## Active production — sourcing on RFQ Sourced to order against BOM quantities — confirm your volume and delivery window with an RFQ.","metaTitle":"SN74F257N 4 x 2:1 Multiplexer 16-DIP Texas Instruments","metaDescription":"Texas Instruments SN74F257N 4 x 2:1 multiplexer, 16-DIP through-hole, 4.5V-5.5V supply, 0°C to 70°C.
