This flexibility makes it useful for applications like serial-to-parallel data conversion, bidirectional data shifting, or as a building block in larger custom shift\/counter circuits. It has parallel data inputs, parallel outputs, a mode control input to select shift direction, and two separate clock inputs (one used for parallel load \/ shift-left, the other for shift-right).\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eCore Operating Modes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eMode\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eCondition\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eBehavior\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eParallel Load\u003c\/td\u003e\n\u003ctd\u003eMode control = HIGH\u003c\/td\u003e\n\u003ctd\u003e4-bit data loaded on high-to-low transition of Clock 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShift Right (QA→QD)\u003c\/td\u003e\n\u003ctd\u003eMode control = LOW\u003c\/td\u003e\n\u003ctd\u003eShifts on high-to-low transition of Clock 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShift Left (QD→QA)\u003c\/td\u003e\n\u003ctd\u003eMode control = HIGH, outputs externally connected QD→C, etc.\u003c\/td\u003e\n\u003ctd\u003eShifts on high-to-low transition of Clock 2, serial data entered at input D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eCore Electrical Ratings\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eParameter\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eSymbol\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eRating\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage Range\u003c\/td\u003e\n\u003ctd\u003eVCC\u003c\/td\u003e\n\u003ctd\u003e2.0V to 6.0V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Bits\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e4-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogic Family\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003eHigh-Speed CMOS (HC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Clock Frequency (typ.)\u003c\/td\u003e\n\u003ctd\u003efmax\u003c\/td\u003e\n\u003ctd\u003e~ MHz range (CMOS HC-series typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePropagation Delay\u003c\/td\u003e\n\u003ctd\u003etPD\u003c\/td\u003e\n\u003ctd\u003eDevice\/family dependent (see datasheet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eESD Protection\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003eStandard HC-series ESD protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature Range\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e-40°C to +85°C (commercial HC-series typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e14-Pin PDIP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eImportant Usage Notes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eCMOS input handling:\u003c\/strong\u003e As with all CMOS logic devices, unused inputs must never be left floating — tie them to VCC or GND as appropriate.
