The 1.27 mm pitch gives the assembler room to route a single trace between pads on a two-layer board. MSL is not explicitly stated in the record, but for a standard SOIC in a 74HC family, the typical rating is MSL 1 — no bake required before reflow if the bag seal is intact. Check the reel label to be sure. ## Logic-level and supply rails The 5.2 mA output drive (both high and low) is enough to fan out to four standard 74HC inputs but not to drive a long backplane trace or a relay coil — plan a buffer if the load exceeds the rated current. If the ambient around the part exceeds 85°C, the 74HC family's propagation delay and output current derate — the datasheet's derating curve is the reference. No stock-holding claim is made; quantities are lot-specific and verified per order.","metaTitle":"Toshiba 74HC157D 4x2:1 Multiplexer, 16-SOIC, 2-6V","metaDescription":"Toshiba 74HC157D quad 2:1 multiplexer in 16-SOIC.

The single independent circuit means all four 2:1 muxes share the same select and enable lines — they switch together, not independently."},{"question":"Will 74HC157D drop into a board designed for 74HC151D?","answer":"No — the 74HC151D is a 1 x 8:1 multiplexer in the same 16-SOIC footprint, but the pinout and function differ. The 74HC157D is a quad 2:1 mux, while the 74HC151D is a single 8:1 mux.
