Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the count-enable (ENP, ENT) inputs and internal gating. This mode of operation eliminates the output counting spikes that are normally associated with synchronous (ripple-clock) counters. A buffered clock input triggers the four flip-flops on the rising (positive-going) edge of the clock waveform. It is fully programmable, that is, it can be preset to any number between 0 and 9 or 15. As presetting is synchronous, setting up a low level at the load input disables the counter and causes the outputs to agree with the setup data after the next clock pulse, regardless of the levels of the enable inputs.\u003c\/strong\u003e\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"features\"\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOutputs can drive up to 10 LSTTL loads\u003c\/li\u003e\n\u003cli\u003eInternal look-ahead for fast counting\u003c\/li\u003e\n\u003cli\u003eCarry output for n-bit cascading\u003c\/li\u003e\n\u003cli\u003eSynchronous counting\u003c\/li\u003e\n\u003cli\u003eSynchronously programmable\u003c\/li\u003e\n\u003cli\u003e80μA Maximum low power consumption\u003c\/li\u003e\n\u003cli\u003e14ns Typical tpd\u003c\/li\u003e\n\u003cli\u003e±4mA Output drive at 5V\u003c\/li\u003e\n\u003cli\u003e1μA Maximum low input current\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cdiv align=\"center\" class=\"datagrid\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/th\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eLogic Family \/ Base Number\u003c\/td\u003e\n\u003ctd\u003e74HC161\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eCounter Type\u003c\/td\u003e\n\u003ctd\u003eBinary\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eClock Frequency\u003c\/td\u003e\n\u003ctd\u003e44MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eCount Maximum\u003c\/td\u003e\n\u003ctd\u003e15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eLogic Case Style\u003c\/td\u003e\n\u003ctd\u003eDIP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eNo. of Pins\u003c\/td\u003e\n\u003ctd\u003e16Pins\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eSupply Voltage Min\u003c\/td\u003e\n\u003ctd\u003e2V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eSupply Voltage Max\u003c\/td\u003e\n\u003ctd\u003e6V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eLogic IC Family\u003c\/td\u003e\n\u003ctd\u003e74HC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eLogic IC Base Number\u003c\/td\u003e\n\u003ctd\u003e74161\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eOperating Temperature Min\u003c\/td\u003e\n\u003ctd\u003e-40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eOperating Temperature Max\u003c\/td\u003e\n\u003ctd\u003e85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eCountry of Origin:\u003c\/td\u003e\n\u003ctd\u003eMalaysia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003cbr\u003e","brand":"Rapidwarehouse","offers":[{"title":"Default Title","offer_id":48100253991177,"sku":"GGBOB370373-RWWS-","price":1.89,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/1747\/2777\/files\/GGBOB370373-1.jpg?v=1720080125","url":"https:\/\/www.rapidwarehouse.com\/products\/4-bit-synchronous-binary-counter-2v-to-6v-dip-16-44mhz-sn74hc161n","provider":"Rapidwarehouse","version":"1.0","type":"link"}
