SN74AHCT540/-Q1 Octal Buffers/Drivers

Texas Instruments SN74AHCT540/-Q1 Octal Buffers/Drivers offer eight inverters with 3-state outputs. The buffers/drivers feature a 540 function that has the same operation as the 240 function, but with a flow-through pinout. The active-low output enable pins (OE1 and OE2) regulate all eight channels and must both be low for the outputs to be active.
