Input logic levels are specified as 0.5 V to 1.65 V for low and 1.5 V to 3.85 V for high, giving it TTL-compatible thresholds that reject noise on slow-rising signals from switches or sensors. ## Propagation delay and output drive for timing closure Maximum propagation delay is 7.5 ns at 5 V with a 50 pF load. This sets the timing budget for the logic path — if the downstream flip-flop has a 2 ns setup time, the OR gate plus interconnect must deliver the signal within 5.5 ns of the clock edge for a single-cycle path. At lower supply voltages the delay increases; at 3.3 V it typically runs about 10 ns. Symmetric output drive of 8 mA source and sink at 5 V means the gate can drive moderate capacitive loads or fan out to four or five standard CMOS inputs without buffering. The quiescent current is just 1 µA maximum, so in a key-off automotive module the gate's own draw is negligible against the system sleep budget. ## Temperature range and deployment in automotive systems For designs targeting 125°C ambient, the SN74AHC1G00DBVT (NAND gate, same family) is rated to 125°C. ROHS3 compliant and free of the six restricted substances plus four phthalates, so it meets the material declarations for automotive OEMs that require full REACH compliance documentation. ## Sourcing and lifecycle position The closest functional peer is the SN74AHC1G32DCKT — same logic function, same 2-input OR gate, same 74AHC family. The package is identical SC-70-5, so a board designed for one accepts the other without layout changes. If your application stays below 85°C, the DCKT is a cost-optimized drop-in.","metaTitle":"SN74AHC1G32TDCKRQ1 OR Gate, SC-70-5, AEC-Q100, 2V-5.5V","metaDescription":"TI SN74AHC1G32TDCKRQ1 single 2-input OR gate, AEC-Q100 automotive grade, SC-70-5 package, 2V-5.5V supply, 7.5ns prop delay, active production, ROHS3.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, 74AHC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Series":"Automotive, AEC-Q100, 74AHC","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"OR Gate","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","lifecycle_stage":"eol_hot","Number of Inputs":"2","Voltage - Supply":"2V ~ 5.5V","Number of Circuits":"1","Operating Temperature":"-40°C ~ 105°C","Input Logic Level - Low":"0.5V ~ 1.65V","Supplier Device Package":"SC-70-5","Input Logic Level - High":"1.5V ~ 3.85V","Current - Quiescent (Max)":"1 µA","Current - Output High, Low":"8mA, 8mA","Max Propagation Delay @ V, Max CL":"7.5ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.41","priceTiers":[{"qty":1,"price":"$0.41000","currency":"USD"},{"qty":3000,"price":"$0.14517","currency":"USD"},{"qty":6000,"price":"$0.13637","currency":"USD"},{"qty":15000,"price":"$0.12757","currency":"USD"},{"qty":30000,"price":"$0.12450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c9d9bb6e1a67ff201964e3a1d18b54bf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74AHC1G32TDCKRQ1/alternatives.json"},"ai":{"faq":[{"question":"Will SN74AHC1G32TDCKRQ1 drop into a board designed for SN74AHC1G32DCKT?","answer":"Yes, the two parts share the same SC-70-5 package and pinout.
