The PI74ALVCH16244AX is a 16-bit buffer/driver with 3-state outputs manufactured by Pericom (now Diodes Incorporated). This device is designed for high-speed, low-power applications requiring minimal signal degradation. It's part of the ALVCH family, which stands for Advanced Low Voltage CMOS with High-Speed, making it suitable for use in systems operating at lower voltages while maintaining high performance.

Applications

• Memory interface
• Data buffering
• Address line driving
• Clock distribution
• General-purpose logic

Features

• 16-bit buffer/driver
• 3-state outputs
• Low voltage operation (typically 3.3V, but can operate at 2.5V)
• High-speed propagation delay
• Low power consumption
• TTL-compatible inputs
• Power-off disable feature

Benefits

• Increased system performance due to fast propagation delays
• Reduced power consumption, extending battery life in portable devices
• Flexible system design with 3-state outputs
• Improved signal integrity due to low output impedance
• Compatibility with TTL logic levels
• Protection against back-drive current during power-off conditions

Additional Details

The PI74ALVCH16244AX operates over a voltage range of 2.3V to 3.6V. It features typical propagation delays of around 3ns, allowing for high-frequency operation. The 3-state outputs allow the device to be effectively disconnected from the bus, enabling multiple devices to share the same bus without contention. The power-off disable feature prevents current backflow when the device is powered down, protecting other components on the bus. The device is available in various surface-mount packages like TSSOP and QVSOP, facilitating easy integration into modern electronic designs. The operating temperature range is typically -40°C to +85°C.
