These counters ensure synchronous operation by clocking all flip-flops simultaneously on the positive-going edge of the clock (CP). The outputs (Q0 to Q3) can be preset to either HIGH or LOW. When the parallel enable input (PE) is LOW, it disables counting and loads the data from the inputs (D0 to D3) into the counter on the clock's positive edge. This presetting occurs regardless of the levels at the count enable inputs (CEP and CET).\u003c\/p\u003e\u003cp\u003eA LOW signal at the master reset input (MR) sets Q0 to Q3 to LOW after the next positive-going clock transition, irrespective of the levels at PE, CET, and CEP. This synchronous reset feature allows for easy modification of the maximum count using only one external NAND gate. The look-ahead carry simplifies the serial cascading of counters. Both CEP and CET must be HIGH for counting to proceed. The CET input enables the terminal count output (TC), which produces a HIGH output pulse approximately equal to a HIGH output of Q0, suitable for enabling the next cascaded stage.\u003c\/p\u003e\u003cp\u003eInputs are equipped with clamp diodes, allowing the use of current limiting resistors to interface inputs to voltages exceeding VCC.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInput levels:\u003cul\u003e\n\u003cli\u003e74HC163: CMOS level\u003c\/li\u003e\n\u003cli\u003e74HCT163: TTL level\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSynchronous counting and loading\u003c\/li\u003e\n\u003cli\u003eTwo count enable inputs for n-bit cascading\u003c\/li\u003e\n\u003cli\u003eSynchronous reset\u003c\/li\u003e\n\u003cli\u003ePositive-edge triggered clock\u003c\/li\u003e\n\u003cli\u003eESD protection:\u003cul\u003e\n\u003cli\u003eHBM JESD22-A114F exceeds 2000V\u003c\/li\u003e\n\u003cli\u003eMM JESD22-A115-A exceeds 200V\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSpecified operating temperature ranges: -40°C to +85°C and -40°C to +125°C\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Voltage:\u003c\/strong\u003e -0.5V to +7.0V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Clamp Current:\u003c\/strong\u003e +20 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Clamp Current:\u003c\/strong\u003e +20 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Current:\u003c\/strong\u003e +25 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Current:\u003c\/strong\u003e 50 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Current:\u003c\/strong\u003e -50 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage Temperature:\u003c\/strong\u003e -65°C to +150°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Power Dissipation:\u003c\/strong\u003e 500 mW\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e1 x 74HC163 Presettable Synchronous Binary Counter IC - SOIC-16 SMD Package\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: Product images are for illustrative purposes only and may differ from the actual product.\u003c\/p\u003e\u003c!----\u003e","brand":"mysite","offers":[{"title":"Default Title","offer_id":46018891382955,"sku":"SMD-QC2311","price":0.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/1205\/1115\/files\/SOIC-16_SMD_Package_0fadf478-991f-438e-a85c-0cbe6ab782dc.jpg?v=1767603462","url":"https:\/\/www.yuzxcn.com\/products\/74hc163-presettable-synchronous-binary-counter-ic-soic-16-smd-package","provider":"Yuzx","version":"1.0","type":"link"}
