The PI74FCT240TQA is an octal buffer/line driver from IDT (Integrated Device Technology). It's part of the FCT (Fast CMOS Technology) family, providing a balance of high-speed operation and low power consumption. The device is designed to improve the performance of memory address drivers, clock drivers, and bus-oriented transmitter/receivers.
Applications
- Memory Address Drivers: Buffering and driving address lines to memory modules.
- Clock Drivers: Distributing clock signals throughout a system with minimal skew and distortion.
- Bus-Oriented Transmitter/Receivers: Interfacing between different bus systems.
- Data Buffering: Temporarily storing data.
- Logic Circuits: General-purpose buffer in digital logic.
Features
- High-Speed Operation: Achieves fast propagation delays due to the FCT technology.
- Low Power Consumption: Minimizes power dissipation.
- Octal Configuration: Handles eight independent channels.
- TTL Compatible Inputs: Interfaces with TTL logic levels.

Additional Details
The PI74FCT240TQA features an active low output enable (OE) input. When OE is high, the outputs are disabled and in a high-impedance state. The device's propagation delay is typically in the nanosecond range. This buffer is designed to minimize ground bounce and ensure clean signal transmission. The specific operating temperature range, supply voltage range, and other electrical characteristics are detailed in the datasheet. This part number is often used in telecommunication, industrial and computer applications where speed is important.
