The PI74FCT240TSX is an octal buffer/line driver with 3-state outputs, manufactured by Pericom Semiconductor (now Diodes Incorporated). Part of the FCT (Fast CMOS Technology) family, this device is designed for high-speed applications requiring signal buffering or line driving capabilities. The '240' designation indicates an inverting buffer/driver.

Additional Details

The PI74FCT240TSX operates from a 5V supply and is typically specified over the industrial temperature range. The device has two output enable (OE) inputs, which control the 3-state outputs. When OE is low, the outputs are enabled and the buffered, inverted signal is present. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus. The inverting nature of the outputs should be considered when designing the system. The low ground bounce characteristic is important for maintaining signal integrity, especially in high-speed applications. Detailed specifications, including propagation delays, power dissipation, and package dimensions, can be found in the manufacturer's datasheet.
