SN74ACT7808-20PAG

FIFOs Memory Overview

The SN74ACT7808-20PAG is a 2048-word by 9-bit strobed first-in, first-out memory device manufactured by Texas Instruments. It utilizes low-power advanced CMOS technology and supports data rates up to 50 MHz with typical access times of 15 ns under a 50-pF load. The component operates within a supply voltage range of 4.5 V to 5.5 V and features an operating temperature range from 0°C to 70°C. It includes three-state outputs, programmable almost-full/almost-empty flags, and expansion logic for depth cascading.

FIFOs Memory Feature Summary

• Provides 2048 words by 9 bits of storage using low-power advanced CMOS technology.
• Features programmable almost-full/almost-empty status flags for buffer management.
• Includes expansion logic allowing for depth cascading of multiple devices.
• Offers three-state outputs controlled by an output enable input.

FIFOs Memory Applications

• High-speed data buffering between asynchronous clock domains
• Depth expansion in FIFO memory chains
• Parallel data processing systems requiring fast access times

FIFOs Memory Procurement Notes

Verify the specific suffix PAG corresponds to the reduced-height 64-pin quad flat package configuration. Confirm that the -20 speed grade matches the required 50 MHz maximum clock frequency and 15 ns typical access time specifications for your application timing constraints.

FIFOs Memory Selection Notes

Select this component when a 9-bit wide FIFO with 2048-word depth is required. Ensure the system design accommodates the 4.5 V to 5.5 V supply voltage range. Consider the 64-pin PAG package dimensions if space constraints are critical, as it offers a reduced height compared to standard QFP packages.

FIFOs Memory Part Context

This part belongs to the SN74ACT7808 family of strobed first-in, first-out memories. The family is characterized by its ability to handle independent load and unload clocks, making it suitable for interface applications where data rates differ between input and output stages.
