SN74ACT7808-30FN

FIFOs Memory Overview

The SN74ACT7808-30FN is a synchronous FIFO memory device manufactured by Texas Instruments. It features a storage capacity of 2048 words by 9 bits and operates within a supply voltage range of 4.5 V to 5.5 V. The component supports data rates up to 33.3 MHz with a maximum access time of 20 ns under a 50-pF load. It utilizes Low-Power Advanced CMOS technology and includes three-state outputs controlled by an output-enable input. The device is housed in a 44-pin Plastic Leaded Chip Carrier (FN) package and is characterized for operation from 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports asynchronous or coincident load and unload clocks for flexible data transfer timing.
• Includes programmable almost-full/almost-empty flags alongside standard full, empty, and half-full status indicators.
• Provides expansion logic enabling depth cascading for increased memory capacity.
• Features three-state outputs to facilitate bus sharing in complex digital systems.

FIFOs Memory Applications

• High-speed data buffering between asynchronous clock domains
• Data rate matching in communication interfaces
• Depth expansion configurations requiring larger buffer capacities

FIFOs Memory Procurement Notes

Verify the specific -30 speed grade suffix against current manufacturer documentation to confirm performance parameters. Confirm the 44-pin FN package type matches the target PCB footprint. Check for end-of-life status or alternative recommendations from Texas Instruments before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when a 2048 x 9 bit synchronous FIFO is required with 33.3 MHz operational limits. Ensure the design accommodates the 4.5 V to 5.5 V supply range and 0°C to 70°C operating temperature. Consider the availability of the 44-pin PLCC package for physical integration constraints.

FIFOs Memory Part Context

This part belongs to the SN74ACT7808 family of strobed first-in, first-out memories. It is designed for high-speed applications using Low-Power Advanced CMOS technology. The family offers various speed grades and package options, including thin quad flat and reduced-height quad flat packages, to suit different system requirements.

FIFOs Memory Replacement Considerations

Consult Texas Instruments documentation for direct replacements or updated alternatives. Verify compatibility regarding pinout, electrical characteristics, and package dimensions if substituting with other FIFO devices.
