The supply range spans 1.65V to 5.5V, covering 1.8V, 2.5V, 3.3V, and 5V logic rails in a single footprint. Symmetric 32 mA source and sink drive gives it enough muscle to fan out to multiple CMOS loads or drive a short PCB trace without a separate line driver. The SC-70-5 package (also known as SOT-353) is a five-lead, 2.0 mm × 1.25 mm body — sized for dense boards where every square millimeter counts. ## Supply range and drive — the BOM-fit numbers At the other end, 5.5V tolerance lets it interface with legacy 5V peripherals or a 5V-regulated bus. The 32 mA output current at both logic levels is symmetric — sourcing and sinking — which simplifies timing analysis because rise and fall times match closely when driving a capacitive load. For a typical 15 pF load at 3.3V, propagation delay stays in the 3–5 ns range (per the family datasheet), which is fast enough for SPI clock rates up to 50 MHz or parallel bus handshaking at tens of megahertz. ## Lifecycle — no obsolescence watch needed This part is current-production from Texas Instruments and suitable for new designs.","metaTitle":"TI 74LVC1G240DCKTG4 Single Inverting Buffer, 1.65V-5.5V","metaDescription":"Texas Instruments 74LVC1G240DCKTG4 single inverting buffer with 3-state output. 32mA drive, 1.65V-5.5V supply, -40°C to 125°C.
