SN74ACT7802-40PN

FIFOs Memory Overview

The SN74ACT7802-40PN is a 1024-word by 18-bit asynchronous FIFO memory manufactured using Low-Power Advanced CMOS technology. It features 3-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device supports data rates up to 40 MHz with typical access times of 30 ns under a 50-pF load. It includes programmable almost-full/almost-empty flags, half-full indicators, and full/empty status signals. The component is housed in an 80-pin Thin Quad Flat (PN) package and is characterized for operation between 0°C and 70°C.

FIFOs Memory Feature Summary

• Supports independent write and read clock domains allowing asynchronous or coincident load and unload operations.
• Provides high-output drive capability suitable for direct bus interfacing applications.
• Includes user-programmable offset values for the almost-full/almost-empty flag status monitoring.

FIFOs Memory Applications

• High-speed data buffering between asynchronous clock domains
• Data rate matching in communication systems
• Parallel data storage in digital signal processing interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix PN confirms the 80-pin Thin Quad Flat package configuration. Ensure the -40 speed grade matches the required timing specifications for your application. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing orders.

FIFOs Memory Selection Notes

Select this component when a wide 18-bit parallel interface is required alongside deep 1024-word storage depth. Consider the 3-state output feature if multiple devices share a common data bus. Evaluate the programmable flag capabilities against system requirements for buffer management and overflow prevention strategies.

FIFOs Memory Part Context

This part belongs to the Texas Instruments Widebus family of logic components. It utilizes Low-Power Advanced CMOS technology to achieve performance levels comparable to older bipolar technologies while maintaining lower power consumption. The device is designed for robust operation in standard industrial temperature ranges.

FIFOs Memory Replacement Considerations

The SN74ACT7802-25PN offers faster switching speeds but may require stricter layout considerations. Verify pinout compatibility and electrical characteristics before substituting with other FIFO variants from different manufacturers.
