74VHC125FT

The Toshiba 74VHC125FT is a high-speed CMOS Quad Bus Buffer featuring non-inverted, 3-state outputs. Fabricated with silicon gate C2MOS technology, it achieves high speed operation while maintaining low power dissipation. The device supports a wide operating voltage range from 2.0 V to 5.5 V, making it suitable for interfacing 5 V to 3 V systems and dual-supply systems.

Key features include a propagation delay time of 3.8 ns (typical) at 5 V, low quiescent current of 4.0 µA (maximum) at 25°C, and high noise immunity. The 74VHC125FT requires the 3-state control input G to be set high to place the output into a high impedance state. An input protection circuit allows 0 to 5.5 V on input pins without regard to the supply voltage, preventing device destruction due to mismatched voltages.

This buffer is supplied in a 14-TSSOP package with a surface mount type. It operates across a wide temperature range of -40°C to 125°C (TA). The device is pin and function compatible with 74 series 125 or 126 type logic.

This component is AEC-Q100 compliant, indicating it meets stringent reliability requirements for automotive applications. Its balanced propagation delays and low noise characteristics make it a reliable choice for various digital circuit designs.
