Texas Instruments SN74LV541A/-Q1 Automotive Octal Buffers/Drivers

Texas Instruments SN74LV541A and SN74LV541A-Q1 Automotive Octal Buffers/Drivers offer 3-state outputs designed for 2V to 5.5V VCC operation. The SN74LV541A-Q1 is AEC-Q100 qualified for automotive applications. The active low output enables pins (OE1 and OE2) to control all eight channels. Furthermore, the TI SN74LV541A and SN74LV541A-Q1 modules are configured so that both must be low for the outputs to be active.
