Housed in a 16-SOIC (0.154\", 3.90mm width) surface-mount package with a 1.27mm pitch. The supplier device package is 16-SOIC, a standard JEDEC outline that places without tombstoning risk on a typical reflow profile. No exposed pad means the thermal path is through the leads only — keep the ambient below 85°C or derate the output current. Supplied in tube packaging. The tube orientation is end-to-end with the pin 1 index at the same end — a pick-and-place feeder changeover between tubes takes one cycle if the tube is loaded correctly. ## Output drive and signal integrity Each output sources or sinks 7.8mA typical at the rated supply voltage. This is enough to drive one or two standard 74HC inputs directly, but a fan-out of more than four loads will stretch the rise time beyond the 6ns typical — buffer the output for a bus with eight receivers. A single independent circuit with four 2:1 multiplexer channels shares a common output enable and select line. The select-to-output propagation delay is typically 15ns at 5V, 50pF load — fast enough for a 20 MHz clock domain but not for a 50 MHz bus without pipeline registers.","metaTitle":"SN74HC258D Texas Instruments Multiplexer, 4x2:1, 16-SOIC","metaDescription":"Active production Texas Instruments SN74HC258D quad 2:1 multiplexer. 2V-6V supply, -40°C to 85°C, 7.8mA output drive. 16-SOIC package.
