74ACT7807-25FN

FIFOs Memory Overview

The SN74ACT7807-25FN is a synchronous FIFO memory integrated circuit manufactured by Texas Instruments. It features an 18K-bit storage capacity organized as 2K words by 9 bits. The device operates with a unidirectional data bus and supports a maximum clock frequency of 25 MHz, achieving a typical access time of 25 ns. It functions within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 400 µA. The component is housed in a 44-pin PLCC package and is rated for operation between 0°C and +70°C.

FIFOs Memory Feature Summary

• Synchronous first-in-first-out memory architecture with 18K-bit capacity
• Supports data rates up to 25 MHz with 25 ns access time
• Unidirectional data bus configuration for single-direction transfer

FIFOs Memory Applications

• High-speed data buffering in digital communication systems
• Clock domain crossing interfaces in asynchronous logic circuits
• Data rate matching between peripheral devices and processors

FIFOs Memory Procurement Notes

Verify the specific suffix 'FN' confirms the 44-pin PLCC package and -25 speed grade. Confirm RoHS compliance status and check for end-of-life notices or alternative sourcing options from authorized distributors. Ensure the operating temperature range meets system requirements.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 9-bit width and 2K depth is required. Compare against other 74ACT78xx variants based on timing speed and pin compatibility. Verify that the 4.5V to 5.5V supply voltage aligns with the target system power rails.

FIFOs Memory Part Context

This part belongs to the Texas Instruments 74ACT78xx family of high-speed synchronous FIFO memories. These components are designed for applications requiring efficient data buffering and flow control. The ACT series offers CMOS performance with TTL-compatible inputs, bridging older logic standards with modern high-speed requirements.

FIFOs Memory Replacement Considerations

Check for direct replacements within the 74ACT7807 series with different speed grades or packages. Verify pin-to-pin compatibility before substituting with similar FIFO ICs from other manufacturers.
