TC74LCX125FT Description

Short technical summary and product information.

The Toshiba TC74LCX125FT is a low voltage, high-speed CMOS quad bus buffer. It operates from a 2.0V to 3.6V supply and features 5.5V tolerant inputs and outputs, enabling interface between 3.3V and 5V systems.

This buffer provides a propagation delay of 6.0 ns maximum at 3.0V to 3.6V VCC. It has an output current capability of 24 mA minimum at 3.0V VCC. The device includes a 3-state control input (OE) which can set the output to a high impedance state. All inputs are protected against electrostatic discharge.

The TC74LCX125FT is available in SOP and TSSOP packages. It is designed for general electronic equipment such as computers, personal devices, office equipment, and industrial robots. The part offers power-down protection on all inputs and outputs.

This buffer is pin-compatible and functionally equivalent to the 74 series 125 type devices (e.g., 74AC/VHC/HC/F/ALS/LS).
