MC74VHC126DTR2G

The MC74VHC126DTR2G from ON Semiconductor is a high-speed CMOS bus buffer designed for efficient signal management. Fabricated with silicon gate CMOS technology, it achieves high speed operation while maintaining low power dissipation.

This device features a 2.0 V to 5.5 V operating range and a 3-state output controlled by an OE input. The inputs are compatible with standard CMOS levels, and the device can function as a level converter for interfacing 3.3 V to 5.0 V systems. Its internal circuits include a buffer output for high noise immunity and stable output. The input structures tolerate voltages up to 5.5 V, enabling the interface of 5 V systems to 3 V systems.

Key electrical characteristics include a typical propagation delay of 3.8 ns at 5.0 V and a low supply current of 4.0 μA maximum at 25°C. It offers high noise immunity with VNIH and VNIL at 28% VCC, and low noise with VOLP at 0.8 V maximum. The device also provides power-down protection on its inputs and has latchup performance exceeding 100 mA.

The MC74VHC126DTR2G is supplied in a 14-TSSOP package, suitable for surface mounting. Its pin and function compatibility with other standard logic families make it a versatile choice for various digital applications.
