It captures data on the positive edge of the clock and holds it until the next clock edge or until the reset line is asserted. The non-inverted outputs drive up to 4 mA per pin, enough for most TTL-level loads or to drive a bus transceiver input. The master reset pin is asynchronous — pulling it low clears all eight registers immediately, regardless of the clock state. This makes the part useful for power-on reset state machines, data latching in microcontroller systems, and address/control register banks in industrial logic. ## Lifecycle and sourcing — active, no LTB risk There is no last-time-buy or end-of-life notice. The part is ROHS3 compliant, so it meets the EU RoHS exemption-free requirements for lead-free assembly.","metaTitle":"SN74HCT273PW TI D-Type Flip-Flop, 37 MHz, 20-TSSOP","metaDescription":"Texas Instruments SN74HCT273PW is an 8-bit D-type flip-flop with master reset, 37 MHz clock, 4.5-5.5V supply, industrial temp range.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"D-Type","Series":"74HCT","Package":"Tube","Function":"Master Reset","Output Type":"Non-Inverted","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Clock Frequency":"37 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Input Capacitance":"3 pF","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-TSSOP","Current - Quiescent (Iq)":"8 µA","Current - Output High, Low":"4mA, 4mA","Number of Bits per Element":"8","Max Propagation Delay @ V, Max CL":"29ns @ 5.5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.33","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.33000","currency":"USD"},{"qty":10,"price":"$1.19100","currency":"USD"},{"qty":25,"price":"$1.13080","currency":"USD"},{"qty":100,"price":"$0.92890","currency":"USD"},{"qty":250,"price":"$0.86828","currency":"USD"},{"qty":500,"price":"$0.76734","currency":"USD"},{"qty":1000,"price":"$0.60579","currency":"USD"},{"qty":2500,"price":"$0.57150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6369628fa72e27b50f21f19876adc052.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SN74HCT273PW and SN74HC273PW?","answer":"The HCT version (SN74HCT273PW) has TTL-compatible input thresholds, while the HC version uses CMOS-level thresholds. In a 5V system driven by TTL outputs, the HCT part provides better noise margin. Both share the same pinout and timing specifications, so they are interchangeable in most designs if the input drive levels are compatible."},{"question":"Is SN74HCT273PW lead-free?","answer":"Yes, the SN74HCT273PW is ROHS3 compliant, meaning it meets the EU RoHS directive for lead-free and other restricted substances."},{"question":"What is the typical propagation delay of 74HCT273?","answer":"The maximum propagation delay is 29 ns at 5.5V supply and 50 pF load.
