Texas Instruments SN74LV8T9541/-Q1 Octal Buffers/Drivers
Texas Instruments SN74LV8T9541/-Q1 Octal Buffers/Drivers contain eight buffers with Schmitt-Trigger inputs and 3-state outputs. The active-low output enable pins (OE1 and OE2) control all eight channels and must both be low for the outputs to be active. When the outputs are enabled, they are actively driven low or high. When outputs are disabled, they are placed in the high-impedance state. The output level supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels and references the supply voltage (VCC).
The input is designed with a lower-threshold circuit to support up translation for lower-voltage CMOS inputs (1.2V input to 1.8V output, or 1.8V input to 3.3V output). In addition, the 5V-tolerant input pins enable down translation (for example, 3.3V to 2.5V output).
The Texas Instruments SN74LV8T9541-EP devices have gold bond wires, a temperature range of –55°C to +105°C, and an SnPb lead finish.
The TI SN74LV8T9541-Q1 is AEC-Q100 qualified for automotive applications.
