The document describes the features and characteristics of the 74V1G125 single bus buffer, including high speed performance, low power dissipation, high noise immunity, power down protection on inputs, symmetrical output impedance, etc.
The 74V1G125 is an advanced high-speed CMOS single bus buffer fabricated with sub-micron silicon gate and double-layer metal wiring CMOS technology. It features a 3-state control input and provides power-down protection on all inputs, allowing 0 to 7V to be accepted on inputs regardless of the supply voltage. This device is suitable for interfacing 5V logic to 3V logic systems.
