Texas Instruments SN74LS157N is the same function and package, so it can serve as a cross-reference in 74LS157 sockets. It is not interchangeable with the 74LS158, which presents inverted data, and it is not a drop-in for 74HC157 or 74S157 devices, which have different electrical characteristics. Use it to replace a failed 74LS157 in vintage computers, arcade boards, and TTL logic repair, and confirm the pinout against your board before installing.\u003cbr\u003e\u003cbr\u003eQ: What does the DM74LS157N replace?\u003cbr\u003eA: Other 74LS157 quad 2:1 data selector\/multiplexers in 16-pin DIP sockets, including SN74LS157N.\u003cbr\u003e\u003cbr\u003eQ: What is the difference between the 74LS157 and the 74LS158?\u003cbr\u003eA: The 74LS157 presents true data at its outputs, while the 74LS158 presents inverted data.\u003cbr\u003e\u003cbr\u003eQ: What supply voltage does it use?\u003cbr\u003eA: It is a 5V TTL part; the Texas Instruments SN74LS157 data lists 4.75V to 5.25V.\u003cbr\u003e\u003cbr\u003eNational Semiconductor DM74LS157N 74LS157 74LS157N IC quad 2-line to 1-line data selector multiplexer 4-channel 2-to-1 multiplexer 16-pin DIP DIP-16 PDIP-16 through-hole 74LS logic low-power Schottky TTL data selector digital logic chip vintage electronics computer arcade repair open box 74LS157 not working replacement multiplexer failed data selector chip replacement arcade board logic chip failed\u003cbr\u003e\u003cbr\u003eThank you for shopping with American Industrial Parts Group!","brand":"National Semiconductor","offers":[{"title":"Default Title","offer_id":49738115645595,"sku":"NSC-DM74LS157N-N","price":4.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/0857\/7435\/files\/national-semiconductor-dm74ls157n-quad-2-1-multiplexer-dip-16-1-american-industrial-parts-group.png?v=1791392337","url":"https:\/\/americanindustrialpartsgroup.com\/products\/national-semiconductor-dm74ls157n-quad-2-1-multiplexer-dip-16-new-open-box","provider":"American Industrial Parts Group","version":"1.0","type":"link"}
