The 74VHC541 is a high-performance CMOS eight-way buffer with three-state outputs. The chip features high speed, low power consumption, high noise immunity and low noise, and is suitable for 5V to 3V voltage interfaces.
The 74VHC541 is an advanced high-speed CMOS octal bus buffer with 3-state outputs, fabricated using sub-micron silicon gate and double-layer metal wiring C7MOS technology. It features a 3-state control gate that operates as two input AND gates, allowing all eight outputs to enter a high impedance state if either G1 or G2 inputs are high. The device offers high noise immunity with a minimum noise margin of 28% of the supply voltage and includes power-down protection on all inputs.
