Product Overview: SN74AS823ADWR - Texas Instruments

The SN74AS823ADWR is a high-performance integrated circuit manufactured by Texas Instruments, a leader in semiconductor design and production. This particular device is part of the advanced Schottky (AS) logic family, which is renowned for its high speed and low power consumption, making it ideal for a wide range of digital applications.

This IC is a 9-bit bus interface flip-flop designed with a clear function, which is essential for initializing the state of the flip-flops during power-up or other reset conditions. The SN74AS823ADWR is characterized by its edge-triggered D-type flip-flops with a direct clear input. The device operates on a 5V power supply, which is a standard logic level in many digital systems.

The product comes in a wide-body SOIC (Small Outline Integrated Circuit) package with 24 pins, denoted by the suffix 'DW'. The 'R' at the end of the part number indicates that the device is provided in tape and reel packaging, which is suitable for automated assembly processes. This packaging ensures safe delivery and efficient handling in high-volume manufacturing environments.

With its fast setup times and high-edge rates, the SN74AS823ADWR is optimized for driving capacitive loads, such as memory address registers, data buses, and other high-capacitance systems. Its buffered outputs reduce the need for external drivers, simplifying design and reducing component count. The device also features a 3-state output stage, which allows for connection to a bus-organized system without the need for additional gating. This feature is particularly useful in bus-oriented applications where multiple devices need to share common data lines.

Texas Instruments ensures that the SN74AS823ADWR meets stringent quality and reliability standards. The device is fully specified for partial-power-down applications using Ioff, which supports live insertion. Its wide operating temperature range makes it suitable for industrial applications, ensuring reliable operation under varying environmental conditions.

Overall, the SN74AS823ADWR from Texas Instruments is a versatile and reliable choice for designers looking to implement high-speed digital logic while maintaining low power dissipation.
