SN74AS876DWG4 - Texas Instruments

The SN74AS876DWG4 is a high-performance, dual 4-bit edge-triggered D-type flip-flop integrated circuit from the renowned semiconductor manufacturer Texas Instruments. This device is designed with advanced Schottky (AS) logic technology, which provides a perfect balance between speed and power consumption, making it suitable for a wide range of high-speed computing and data processing applications.

Featuring two individual 4-bit flip-flops with single-rail outputs, the SN74AS876DWG4 is capable of storing up to 8 bits of data. Each flip-flop has independent data (D), clock (CLK), set (SET\), and reset (RESET\) inputs. The clock triggering occurs at the clock pulse's rising edge, ensuring precise timing for data capture. The SET\ and RESET\ inputs are active low and are used to set or reset the flip-flops, respectively, without regard to the state of the clock.

The device comes in a wide-body SOIC (DW) package with 24 pins, offering a compact footprint for space-constrained applications. The SN74AS876DWG4 operates over a broad supply voltage range from 4.5V to 5.5V, which is typical for 5V logic families. This allows for easy integration into existing 5V systems without the need for additional level-shifting components.

Key features of the SN74AS876DWG4 include its high-speed performance, with typical shift/frequency response exceeding 100 MHz, and its low power Schottky circuitry which minimizes power dissipation even at high frequencies. The device also has a high noise immunity characteristic of the AS logic family, making it reliable in electrically noisy environments.

Applications for the SN74AS876DWG4 are diverse, ranging from high-speed data capture systems, temporary data storage in computing and digital signal processing, to communication systems where reliable and fast data handling is crucial. Texas Instruments' commitment to quality ensures that this flip-flop meets stringent standards for performance and reliability, making it a trusted choice for engineers and designers alike.
