It accepts a single input and delivers the inverted logic level at its output, which can be placed into a high-impedance state (Hi-Z) for bus isolation or shared-line applications. The 3-state control is active-low on the output enable, allowing multiple devices to drive a common bus without contention. The supply range spans 1.65V to 5.5V, making it compatible with 1.8V, 2.5V, 3.3V, and 5V logic domains without an external level translator. This wide operating window suits mixed-voltage boards where a single part must bridge different power rails. Output drive capability is 32mA for both high and low states, enough to directly drive small loads such as LEDs, relay coils, or multiple CMOS gate inputs. The 3-state output also supports wired-OR or bidirectional bus structures when the enable signal is managed by a microcontroller or system controller. ## Package and footprint — SC-70-5 The 74LVC1G240DCKRE4 is supplied in a 5-lead SC-70-5 package (also known as SOT-353). No special handling beyond standard MSL precautions is required for this package.","metaTitle":"74LVC1G240DCKRE4 Buffer Inverting 3-State, 1.65V-5.5V","metaDescription":"74LVC1G240DCKRE4 single inverting buffer with 3-state output, 1.65V to 5.5V supply, 32mA drive, -40°C to 125°C.
