The SN74LVC540ANSR is a Octal Buffer/Driver with 3-State Outputs, manufactured by Texas Instruments. It is a low-voltage CMOS device, operating with a supply voltage between 2.3V and 3.6V, allowing it to be used for 1.65V to 3.6V VCC operation, and supporting live insertion/extraction.This device features two independent data flow paths, from input to output, and has 3-state outputs for bus-oriented applications. Each output can assume three states: low, high, or high-impedance, allowing multiple drivers to be connected to a single output line. The SN74LVC540ANSR is designed to hold signals for high-speed data bus transmission, due to the low propagation delay and minimal undershoot and overshoot.
