The photographed unit is marked 74S273N, K8322, and SA on top with a green dot, and 4S273-F, 46, and E on the underside.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003eEight D-type flip-flops in one package.\u003cbr\u003ePositive-edge-triggered.\u003cbr\u003eBuffered clock and direct clear inputs.\u003cbr\u003eIndividual data input to each flip-flop.\u003cbr\u003eSingle-rail outputs.\u003cbr\u003eSchottky TTL for high-speed operation.\u003cbr\u003e\u003cbr\u003eCompatibility:\u003cbr\u003eDirect replacement for 74S273N and N74S273N in 20-pin sockets designed for the 74273 pinout. The 74LS273, 74ALS273, and 74F273 share the same octal D flip-flop function in other logic families. Check speed and drive requirements before substituting across families. Common in buffer and storage registers, shift registers, and pattern generators in vintage computer, arcade, and test equipment boards.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A:\u003cbr\u003eQ: What does the 74S273 do?\u003cbr\u003eA: It stores 8 bits of data on the rising edge of the clock and has a direct clear input that resets all outputs.\u003cbr\u003e\u003cbr\u003eQ: Can I use a 74LS273 instead?\u003cbr\u003eA: It has the same function in a lower-power family. Confirm your circuit's speed and drive requirements before substituting.\u003cbr\u003e\u003cbr\u003eQ: What does K8322 mean?\u003cbr\u003eA: 8322 is the date code (1983, week 22).\u003cbr\u003e\u003cbr\u003eTroubleshooting:\u003cbr\u003eCheck the supply voltage at the VCC and ground pins.\u003cbr\u003eHold the clear input inactive during normal operation.\u003cbr\u003eConfirm data is stable before the rising clock edge.\u003cbr\u003eCompare outputs against the datasheet function table.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003ePlease review all photos and specifications before purchasing, and make sure this part is right for your application.
