It mates with 20-pin DIP sockets or can be soldered directly. The 8mA output drive per channel is adequate for point-to-point logic links and short bus segments; for heavily loaded backplanes or long cables, a higher-drive family (e.g., 74ABT with 32mA output) would be needed. ## Lifecycle and compliance No end-of-life notice or last-time-buy schedule is in effect. For new designs, it remains a valid choice; for existing BOMs, no supply-risk flag is raised.","metaTitle":"SN74AHC245N 74AHC Transceiver, 8-Bit, 3-State, 20-DIP","metaDescription":"SN74AHC245N from TI's 74AHC series: 8-bit non-inverting transceiver with 3-state outputs, 2V–5.5V supply, 8mA drive, through-hole 20-DIP, industrial temp range.","metaKeywords":null},"attributes":{"series":"74AHC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74AHC","Package":"Tube","Logic Type":"Transceiver, Non-Inverting","Output Type":"3-State","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 5.5V","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"20-PDIP","Current - Output High, Low":"8mA, 8mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.80000","currency":"USD"},{"qty":10,"price":"$0.70000","currency":"USD"},{"qty":25,"price":"$0.65720","currency":"USD"},{"qty":100,"price":"$0.53640","currency":"USD"},{"qty":250,"price":"$0.49820","currency":"USD"},{"qty":500,"price":"$0.42400","currency":"USD"},{"qty":1000,"price":"$0.33920","currency":"USD"},{"qty":2500,"price":"$0.30740","currency":"USD"},{"qty":5000,"price":"$0.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e8972affec2d3dcdc8abec147c2380e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I use SN74AHC245N as a replacement for 74HC245?","answer":"Yes, the SN74AHC245N is a direct functional replacement for the 74HC245 in most designs. The AHC series offers higher speed and lower power consumption while maintaining pin compatibility and the same 2V to 5.5V supply range. Verify the output drive (8mA) meets your load requirements."},{"question":"Is SN74AHC245N pin compatible with SN74HCT245N?","answer":"Yes, the SN74AHC245N is pin compatible with the SN74HCT245N. Both are 20-pin DIP transceivers with the same DIR and OE control logic. The AHC variant operates from 2V to 5.5V, while HCT is optimized for 5V TTL-compatible inputs."},{"question":"What is the closest functional second-source for SN74AHC245N?","answer":"The SN74ABT2245DW is a surface-mount (SOIC) 8-bit transceiver with higher output drive (32mA) but a fixed 4.5V supply and commercial temperature range (0°C to 70°C). It is not a pin-compatible drop-in due to package differences, but it fills the same bus-transceiver role for high-drive, 5V-only designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AHC245N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AHC245N when reusing this data.
