MC74VHC126DR2G

The MC74VHC126DR2G is a high-speed CMOS quad bus buffer manufactured by ON Semiconductor. Fabricated with silicon gate CMOS technology, it achieves high speed operation while maintaining low power dissipation. This device features non-inverting logic with 3-state control inputs, requiring the OE (Output Enable) to be set High to place the output into a high impedance state.

Key electrical characteristics include a wide operating voltage range of 2.0V to 5.5V and output current capabilities of 8mA for both high and low states. The inputs are compatible with standard CMOS levels, and the device offers high noise immunity with VNIH and VNIL at 28% of VCC. It also provides power-down protection on inputs and has a propagation delay of 3.8 ns typical at 5.0V.

This buffer is supplied in a 14-SOIC surface mount package. Its design allows for interfacing 3.3V systems to 5.0V systems due to its full 5.0V CMOS level output swings. The internal circuits consist of three stages, including a buffer output for high noise immunity and stable output.

The MC74VHC126DR2G is suitable for various digital logic applications requiring high-speed buffering and signal control. Its pin and function compatibility with other standard logic families make it a versatile component for circuit design.
