TC74VHCT126AF Description

Short technical summary and product information.

The Toshiba TC74VHCT126AF is a high-speed CMOS Quad Bus Buffer fabricated using silicon gate C2MOS technology. It achieves high-speed operation comparable to bipolar Schottky TTL while maintaining low CMOS power dissipation. This device is suitable for interfacing 3.3 V to 5 V systems due to its TTL-compatible input voltage levels.

 

Key electrical characteristics include a typical propagation delay of 3.8 ns at 5 V supply and a maximum supply current of 4 μA at 25°C. The input voltage tolerance ranges from -0.5 V to 7.0 V, and output voltage tolerance is also -0.5 V to 7.0 V, providing protection against mismatched supply and I/O voltages.

 

Available in SOP14 and VSSOP14 packages, this Quad Bus Buffer is designed for surface mount applications. Its pin and function compatibility with the 74 series 126 type simplifies integration into existing designs.
