SN74ACT7201LA20NP

FIFOs Memory Overview

The SN74ACT7201LA20NP is an asynchronous, uni-directional FIFO memory component manufactured by Texas Instruments. It provides a total memory capacity of 4.5K bits, organized as 512 words by 9 bits. The device operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 28-pin PDIP package. It supports data rates up to 5 million words per second with a 5 MHz write clock and processes data at 3 million words per second with a 3 MHz read clock.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent write and read clock domains for flexible interface integration.
• Uni-directional data flow simplifies design for single-path buffering applications.
• CMOS output structure ensures high noise immunity and low power consumption.

FIFOs Memory Applications

• Buffering data between asynchronous logic systems
• Level shifting between different voltage domains
• Data rate matching in communication interfaces

FIFOs Memory Procurement Notes

Verify the exact suffix 'A20NP' corresponds to the 28-pin PDIP package and specific speed grade. Confirm RoHS compliance status through official TI documentation or authorized distributor certificates before procurement. Ensure the ordering part number matches the required pin configuration and electrical specifications exactly.

FIFOs Memory Selection Notes

Select this component when an asynchronous, uni-directional FIFO with 9-bit word width is required. Consider the 512-word depth for moderate buffering needs. Verify that the 4.5V to 5.5V operating range aligns with the system power supply. Check if the 28-pin DIP package fits the PCB layout constraints compared to surface-mount alternatives.

FIFOs Memory Part Context

This part belongs to the SN74ACT series of advanced CMOS logic devices from Texas Instruments. The ACT series offers higher speed and lower power consumption compared to standard AC logic families. As a FIFO memory IC, it serves as a critical interface element for managing data flow in digital systems requiring temporary storage and synchronization.

FIFOs Memory Replacement Considerations

Check for SN74ACT7201 variants with different suffixes indicating alternative packages or speeds. Verify compatibility with SN74FCT series if faster performance is needed, noting potential pinout differences. Consult TI's cross-reference tools for direct functional equivalents with identical memory organization and interface characteristics.
