SN74ACT7201LA25NP

FIFOs Memory Overview

The SN74ACT7201LA25NP is an asynchronous FIFO memory component from Texas Instruments, packaged in a 28-DIP (PDIP) housing. It provides a unidirectional memory depth of 512 words with a 9-bit data width, totaling 4.5K bits. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 28.5 MHz. Key electrical characteristics include a propagation delay of 25 ns and output drive capabilities of ±24 mA. It features automatic retransmission functionality and output enable controls.

FIFOs Memory Feature Summary

• Asynchronous first-in, first-out memory architecture for buffering data between unsynchronized domains
• Automatic retransmission function to manage data flow integrity
• Output enable control for bus isolation management
• CMOS output structure with TTL-compatible input levels

FIFOs Memory Applications

• Embedded systems requiring data buffering
• Industrial automation signal processing
• General-purpose electronics interfacing

FIFOs Memory Procurement Notes

Verify the specific suffix 'A25' corresponds to the required 25 ns speed grade and 28-DIP package variant. Confirm RoHS compliance status and lead content declarations as indicated in distributor listings. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design integration.

FIFOs Memory Selection Notes

Select this component when a unidirectional asynchronous buffer with 9-bit word width is required. The 28.5 MHz operating frequency suits moderate-speed data transfer applications. Consider the through-hole DIP-28 package if prototyping or legacy board layouts necessitate manual insertion rather than surface-mount technology.

FIFOs Memory Part Context

This part belongs to the SN74ACT series of advanced CMOS logic devices, designed for high-speed operation with low power consumption. The SN74ACT7201LA family includes variants with different depths such as 256x9 and 1024x9 configurations. The LA25NP designation specifically identifies the 512x9 capacity with the specified timing and packaging constraints.

FIFOs Memory Replacement Considerations

Compatible substitutes within the same family include SN74ACT7201LA variants with different speed grades or package options, provided the 512x9 depth and unidirectional nature are maintained. Verify pin compatibility before substitution.
