Texas Instruments SN74LS74AN, Motorola SN74LS74AN, and Signetics 74LS74AN are the same function and package, so each can serve as a cross-reference for the others in 74LS74 sockets. It is not a drop-in for 74HC74 or 74S74 devices, which have different electrical characteristics. Use it to replace a failed 74LS74 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 DM74LS74AN replace?\u003cbr\u003eA: Other 74LS74 dual D flip-flops in 14-pin DIP sockets, including SN74LS74AN and 74LS74AN.\u003cbr\u003e\u003cbr\u003eQ: What supply voltage does it use?\u003cbr\u003eA: It is a 5V TTL part; the Texas Instruments SN74LS74A datasheet lists 4.75V to 5.25V.\u003cbr\u003e\u003cbr\u003eQ: Is it tested?\u003cbr\u003eA: No electrical testing is represented.
