It selects one of two 4-bit data sources onto a common output bus under control of a single select line. ## Output drive and fan-out Each output can sink or source 8mA (typical) — enough to drive three or four standard LSTTL loads or a single 74AHCT input with margin. If you are driving a heavily loaded bus or a long backplane trace, plan a buffer stage; the 8mA rating is the limit per pin. ## Active production — no end-of-life concern The SN74AHCT157N carries an Active product status, meaning TI continues to manufacture it without a last-time-buy window. For a BOM line that needs a DIP-format multiplexer, this part is a low-risk choice for both new builds and sustaining production.","metaTitle":"SN74AHCT157N 74AHCT Quad 2:1 Multiplexer, 4.5V-5.5V, 16-DIP","metaDescription":"SN74AHCT157N is a 4 x 2:1 multiplexer from TI's 74AHCT family.
