Data meeting setup time requirements on the D inputs is transferred to the Q outputs on the rising edge of the clock (CLK). The CLR input, when asserted low, overrides the clock and clears all Q outputs to low. With a wide operating voltage range of 2V to 6V and 12 ns typical propagation delay, this device is ideal for high-speed digital storage applications.","working_principle":"The SN74HC273NSR operates as an 8-bit edge-triggered register. On the rising edge of the CLK input, the logic levels present at the eight D inputs are captured and appear at the corresponding Q outputs. When CLK is static (high or low), the D inputs have no effect on the outputs. The CLR input provides asynchronous reset: when CLR is low, all Q outputs are forced low regardless of CLK or D input states. This makes the device suitable for both synchronous data latching and system initialization through the clear function.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>CLR<\/td><td>Input<\/td><td>Direct clear (active low)<\/td><\/tr><tr><td>2<\/td><td>1Q<\/td><td>Output<\/td><td>Flip-flop 1 output<\/td><\/tr><tr><td>3<\/td><td>1D<\/td><td>Input<\/td><td>Flip-flop 1 data input<\/td><\/tr><tr><td>4-9<\/td><td>2Q-5Q<\/td><td>Output<\/td><td>Flip-flops 2-5 outputs<\/td><\/tr><tr><td>10<\/td><td>GND<\/td><td>Ground<\/td><td>Ground reference<\/td><\/tr><tr><td>11<\/td><td>CLK<\/td><td>Input<\/td><td>Clock input (rising edge triggered)<\/td><\/tr><tr><td>12-19<\/td><td>6D-8Q\/6Q-8D<\/td><td>I\/O<\/td><td>Flip-flops 6-8 data\/outputs<\/td><\/tr><tr><td>20<\/td><td>VCC<\/td><td>Power<\/td><td>Supply voltage 2-6V<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Microprocessor address\/data latch registers<\/li><li>Digital storage and buffer registers<\/li><li>Pattern generation for display systems<\/li><li>Parallel data capture and hold<\/li><li>General-purpose synchronous digital storage<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>SN74HC273DW<\/td><td>SOIC-20<\/td><td>Wider SOIC package<\/td><\/tr><tr><td>TI<\/td><td>SN74HC273N<\/td><td>PDIP-20<\/td><td>Through-hole version<\/td><\/tr><tr><td>TI<\/td><td>SN74HCT273NSR<\/td><td>SOP-20<\/td><td>TTL-compatible inputs<\/td><\/tr><tr><td>NXP<\/td><td>74HC273D<\/td><td>SOIC-20<\/td><td>Pin-compatible alternative<\/td><\/tr><tr><td>TI<\/td><td>SN74HC273PWR<\/td><td>TSSOP-20<\/td><td>Smaller TSSOP package<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3015","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=3015"}],"version-history":[{"count":2,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3015\/revisions"}],"predecessor-version":[{"id":3046,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3015\/revisions\/3046"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=3015"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=3015"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=3015"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=3015"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
