IDT7204L20SO8

FIFOs Memory Overview

The IDT7204L20SO8 is an asynchronous First-In-First-Out (FIFO) memory device manufactured by Renesas Electronics. It features a storage organization of 4K words by 9 bits, providing a total capacity of 36 kilobits. The component supports a maximum access time of 20 nanoseconds and operates on a single 5-volt CMOS supply. It is housed in a 28-pin Small Outline Integrated Circuit (SOIC) package with an 8-mil body width.

FIFOs Memory Feature Summary

• Asynchronous operation allowing independent read and write clock domains for flexible data buffering
• CMOS technology ensuring low power consumption during active and deselected states
• Dedicated status flags including Full, Empty, Almost-Full, and Almost-Empty for flow control

FIFOs Memory Applications

• Interprocessor communication interfaces requiring data rate mismatch handling
• Local Area Network (LAN) packet buffering systems
• Graphics controller data buffering applications

FIFOs Memory Procurement Notes

Verify the specific suffix SO8 against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as manufacturing sources may vary. Check current lifecycle status, as this part number may be subject to discontinuation or obsolescence notices from the manufacturer.

FIFOs Memory Selection Notes

Select this component when a 4Kx9 asynchronous FIFO with 20ns speed is required. Ensure the system voltage matches the 5V specification. Verify that the 28-pin SOIC package dimensions fit the target PCB layout constraints compared to alternative packages like LCC or DIP.

FIFOs Memory Part Context

This device belongs to the 7204L series of high-speed asynchronous FIFOs. The series typically includes variants with different access times and package options, such as the 7204L12 and 7204L20 models, designed for various buffering needs in digital logic applications.

FIFOs Memory Replacement Considerations

Official cross-reference documents indicate that the IDT7204L20LB serves as a functional equivalent within the same product family. Verify pin-to-pin compatibility and parameter alignment before substitution.
