Each gate accepts one input and inverts it; the open-collector output means the high-side transistor is absent, so the output can sink current to ground but cannot source it — the load must pull up to a positive rail. The open-collector output can sink up to 16 mA per channel when low, but the high-level current is zero — the external pull-up resistor determines the high-state voltage and the current sourced from the load supply. ROHS3 compliance is confirmed, so it meets the latest EU restriction directive for lead and other substances. Because it is an active, standard-logic part, it is widely available through multiple distribution channels.","metaTitle":"SN7405N Texas Instruments 7400 Hex Inverter, Open Collector","metaDescription":"SN7405N is a 7400-series hex inverter with open-collector outputs in a 14-DIP package. 6 circuits, 4.75–5.25 V supply, 55 ns propagation delay.","metaKeywords":null},"attributes":{"series":"7400","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"7400","Package":"Tube","Features":"Open Collector","Logic Type":"Inverter","Mounting Type":"Through Hole","Package / Case":"14-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Number of Inputs":"1","Voltage - Supply":"4.75V ~ 5.25V","Number of Circuits":"6","Operating Temperature":"0°C ~ 70°C","Input Logic Level - Low":"0.8V","Supplier Device Package":"14-PDIP","Input Logic Level - High":"2V","Current - Quiescent (Max)":"12 mA","Current - Output High, Low":"-, 16mA","Max Propagation Delay @ V, Max CL":"55ns @ 5V, 15pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.12","priceTiers":[{"qty":1,"price":"$2.12000","currency":"USD"},{"qty":10,"price":"$1.90700","currency":"USD"},{"qty":25,"price":"$1.79920","currency":"USD"},{"qty":100,"price":"$1.53300","currency":"USD"},{"qty":250,"price":"$1.43948","currency":"USD"},{"qty":500,"price":"$1.25954","currency":"USD"},{"qty":1000,"price":"$1.04362","currency":"USD"},{"qty":2500,"price":"$1.01850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/42a89b0cd2ad29f9fe30bcfdc5d87a13.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN7405N/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for SN7405N?","answer":"No official manufacturer replacement or successor is listed for the SN7405N.
