Single inverting buffer with 3-state — what the 32 mA drive means on a mixed-voltage bus
The SN74LVC1G240DCKR is a single inverting buffer from TI's 74LVC series, with a 3-state output that lets you float the line when the OE pin is high — useful for shared data buses where multiple drivers need to take turns. Output drive is 32 mA source and 32 mA sink at 3.3 V — enough to charge the gate of a small MOSFET or drive a short unterminated trace on a board-level bus, but not enough for a long backplane without a line driver or series termination.
