Texas Instruments 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.
The TI SN74AHC540-Q1 devices are AEC-Q100 qualified for automotive applications.
