SNx4AHC540/SNx4AHC540-Q1 Octal Buffers/Drivers

Texas Instruments SNx4AHC540/SN74AHC540-Q1 Octal Buffers/Drivers offer eight inverters with 3-state outputs. The Buffers/Drivers feature a 540 function that has the same functionality as the 240 function, but with a flow-through pinout. The active low output enable pins (OE1 and OE2) manage all eight channels and are configured so that both must be low for the outputs to be active.
