SN74ALVCH244NSRG4 Octal Buffer/Driver by Texas Instruments

The SN74ALVCH244NSRG4 is a high-performance, octal buffer and driver designed to facilitate the transfer of data from one part of a system to another. Manufactured by Texas Instruments, this integrated circuit is part of the ALVCH family, which is known for its low-voltage operation and high-speed interface technology. The device is particularly suitable for implementing buffer functions in systems that require a high degree of signal integrity.

This device features eight non-inverting buffers and drivers with 3-state outputs. The 3-state outputs allow for connection to a bus or for creating multiplexed data lines, offering versatility in usage. The SN74ALVCH244NSRG4 operates at a nominal voltage of 2.5V to 3.6V, which makes it compatible with low-voltage systems and helps in reducing power consumption.

The product is available in a 20-pin NSR (Shrink Small-Outline) package, ensuring a compact footprint on printed circuit boards (PCBs). This package type is ideal for space-constrained applications where board real estate is at a premium. The NSR package also provides improved electrical performance due to its smaller lead inductances.

Key features of the SN74ALVCH244NSRG4 include:

• High drive capability, with ±24-mA output drive at 3.3V.
• Low input capacitance, which minimizes loading on data lines.
• IOFF and power-up 3-state support, which prevents unwanted data flow during power up or power down.
• Support for live insertion and withdrawal without glitching or power-down issues.
• Latch-up performance that exceeds 250 mA per JESD 17, ensuring robustness in complex systems.
• ESD protection exceeding JESD 22, safeguarding the device from electrostatic discharges during handling and operation.

The SN74ALVCH244NSRG4 is designed for a wide array of applications, including memory address driving, bus isolation, and buffering in servers, telecommunications, and computing environments where signal integrity and low power are essential. Its high-speed interface technology makes it an excellent choice for interfacing with high-speed microprocessors and reducing signal distortion in critical paths.

With Texas Instruments' commitment to quality and long-term reliability, the SN74ALVCH244NSRG4 is a dependable solution for designers looking to optimize their digital systems for performance and power efficiency.
