The SN74AHCT540-Q1 contains eight inverters with 3-state outputs. The 540 function has the same functionality as the 240 function and has a flow-through pinout. The active low output enable pins (OE1 and OE2) control all eight channels, and are configured so that both must be low for the outputs to be active.
