7204L20TDB

Overview

The Renesas Electronics Corporation 7204L20TDB is a 36K (4K x 9) uni-directional asynchronous FIFO memory device. It operates with a maximum data rate of 33.3MHz and features an access time of 20ns. The component is housed in a 28-CDIP package with dimensions of 0.300 inches (7.62mm). It requires a supply voltage range of 4.5V to 5.5V and supports through-hole mounting.

Feature Summary

• Uni-directional asynchronous data buffering architecture
• CMOS parallel interface technology
• Through-hole dual in-line package construction

Applications

• High-speed digital signal processing interfaces
• Data acquisition system buffering
• Communication protocol conversion stages

Procurement Notes

Verify the obsolete status and discontinuance notification before procurement planning. Confirm RoHS compliance requirements as the component may not meet current environmental standards. Validate pin compatibility and electrical specifications against target designs due to potential manufacturing changes or end-of-life constraints.

Selection Notes

Select this component for applications requiring reliable 4K x 9 depth buffering with 20ns latency. Ensure the design accommodates the 28-CDIP form factor and 4.5V to 5.5V power supply range. Consider the uni-directional nature of the data flow when designing the system architecture.

Part Context

This part belongs to the 7204L series of asynchronous FIFOs from Renesas Electronics. It shares architectural similarities with other members like the 7204L15 and 7204L30, differing primarily in speed grades and package options. The series provides standard parallel FIFO functionality for memory interfacing.

Replacement Considerations

Renesas recommends the 7204L12JG as a manufacturer-recommended substitute. Verify functional equivalence and pinout compatibility before substitution.
