Texas Instruments SN74LV8T245/SN74LV8T245-Q1 Octal Bus Transceiver

Texas Instruments SN74LV8T245/SN74LV8T245-Q1 Octal Bus Transceiver comes with 3-state outputs and all eight channels are controlled by the direction (DIR) pin and output enable (OE) pin. The output level is referenced to the supply voltage (V_CC) and supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels. The input is designed with a lower threshold circuit to support up translation for lower voltage CMOS inputs (for example, 1.2V input to 1.8V output or 1.8V input to 3.3V output). The 5V tolerant input pins also enable down translation (for example, 3.3V to 2.5V output). The Texas Instruments SN74LV8T245-Q1 devices are AEC-Q100 qualified for automotive applications.
