The outputs (Q0 to Q3) of the counters may be preset HIGH or LOW.\u003cbr\u003e\r\nA LOW at the parallel enable input (PE) disables the counting action and causes the data at the data inputs (D0 to D3) to be loaded into the counter on the positive-going edge of the clock.

Both CEP and CET must be HIGH to count. The CET input is fed forward to enable the terminal count output (TC). The TC output thus enabled will produce a HIGH output pulse of a duration approximately equal to a HIGH output of Q0. This pulse can be used to enable the next cascaded stage. The \u003cstrong\u003emaximum clock frequency\u003c\/strong\u003e for the cascaded counters is determined by the CP to TC propagation delay and CEP to CP set-up time.\u003cbr\u003e\r\nInputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.\u003c\/span\u003e\u003c\/p\u003e\r\n\r\n\u003ch2\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e:\u003c\/h2\u003e\r\n\r\n\u003col\u003e\r\n\t\u003cli\u003eComplies with JEDEC standard no. 7A\u003c\/li\u003e\r\n\t\u003cli\u003eCMOS input levels\u003c\/li\u003e\r\n\t\u003cli\u003eSynchronous counting and loading\u003c\/li\u003e\r\n\t\u003cli\u003eTwo count enable inputs for n-bit cascading\u003c\/li\u003e\r\n\t\u003cli\u003eAsynchronous reset\u003c\/li\u003e\r\n\t\u003cli\u003ePositive-edge triggered clock\u003c\/li\u003e\r\n\t\u003cli\u003eESD protection:\u003c\/li\u003e\r\n\t\u003cli\u003eHBM JESD22-A114F exceeds 2000 V\u003c\/li\u003e\r\n\t\u003cli\u003eMM JESD22-A115-A exceeds 200 V\u003c\/li\u003e\r\n\t\u003cli\u003eMultiple package options\u003c\/li\u003e\r\n\t\u003cli\u003eSpecified from -40 °C to +85 °C and -40 °C to +125 °C\u003c\/li\u003e\r\n\u003c\/ol\u003e\r\n\r\n\u003ch2\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h2\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003ePresettable synchronous 4 bit binary counter\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch2\u003e\u003cstrong\u003eDataSheet:\u003c\/strong\u003e\u003c\/h2\u003e\r\n\r\n\u003cp\u003e\u003cimg src=\"https:\/\/digilog.pk\/cdn\/shop\/files\/pdf.jpg\" data-original=\"https:\/\/www.electronicscomp.com\/image\/catalog\/pdf.jpg\" alt=\"74hc161 Ic Presettable Synchronous 4 Bit Binary Counter\" loading=\"lazy\" data-files=\"pdf.jpg\"\u003e\u003ca href=\"https:\/\/assets.nexperia.com\/documents\/data-sheet\/74HC161.pdf\" title=\"74hc161 datasheet\" aria-label=\"Visit a webpage about 74hc161 datasheet\"\u003e74HC161 Datasheet\u003c\/a\u003e\u003c\/p\u003e\r\n\r\n\u003ch2\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e\u003c\/h2\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003e1 x 74hc161 IC \u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e","brand":"China","offers":[{"title":"Default Title","offer_id":43962332479553,"sku":"B67,DELL","price":250.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/2805\/1777\/files\/74HC161_IC_Presettable_synchronous_4-bit_binary_counter_in_Pakistan.jpg?v=1779568921","url":"https:\/\/stem.pk\/products\/74hc161-ic-presettable-synchronous-4-bit-binary-counter-in-pakistan","provider":"stem.pk","version":"1.0","type":"link"}
