Texas Instruments SN74LV8T540/-Q1 Octal Inverting Buffer/Drivers
Texas Instruments SN74LV8T540/-Q1 Octal Inverting Buffer/Drivers feature eight inverters with 3-state outputs. The device offers a 540 function with the same capabilities as the 240 function, but with a flow-through pinout. The active-low output enable pins (OE1 and OE2) control all eight channels and must both be low for the outputs to be active. The input is developed with a reduced-threshold circuit to support up translation when the supply voltage is greater than the input voltage. Furthermore, the 5V-tolerant input pins allow down-translation when the input voltage exceeds the supply voltage. The output level is always referenced to the supply voltage (VCC) and supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels.
The TI SN74LV8T540/-Q1 Buffer/Drivers are AEC-Q100 qualified for automotive applications.
