The two elements, each handling four bits, provide eight inverting channels with a balanced 7.8mA sink and source drive at both output states. The wide temperature grade eliminates the need to derate or qualify a separate industrial-tier variant for mixed-temperature BOM lines. ## 20-DHVQFN with exposed pad — layout notes The 0.5 mm pitch fine-pitch QFN calls for a controlled impedance PCB if the bus traces run longer than a few centimetres at 5V edge rates. The supplier device package is 20-DHVQFN (4.5x2.5). Listed with an active product status, the 74HC240BQ carries no last-time-buy or end-of-life notice. For production BOMs that need a second-source hedge, the 74HC240 footprint is broadly second-sourced across multiple logic vendors — qualify an alternate now rather than single-source it.","metaTitle":"74HC240BQ/C4115 Buffer, Inverting 3-State, 2V-6V, 20-DHVQFN","metaDescription":"74HC240BQ/C4115 octal inverting buffer with 3-state outputs. 2V to 6V supply, -40°C to 125°C.
