7205L12PDG

Overview

The Renesas Electronics Corporation 7205L12PDG is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 8K x 9 bits. It operates with a maximum access time of 12 nanoseconds and supports unidirectional data transfer at frequencies up to 33.3 MHz. The device functions within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum current of 120 mA. It is housed in a 28-pin PDIP package suitable for through-hole mounting and complies with lead-free standards.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface integration
• Unidirectional architecture simplifies design for standard buffer applications
• Relay capability allows signal pass-through during specific operational states

Applications

• Data buffering between systems operating at different clock speeds
• Interface bridging in high-speed digital communication links
• Temporary data storage in microprocessor-based control systems

Procurement Notes

Verify component authenticity due to discontinuation status. Confirm RoHS compliance and moisture sensitivity handling requirements. Check for valid replacement part numbers from authorized distributors as original stock may be limited or unavailable.

Selection Notes

Select this component when unidirectional asynchronous buffering is required with 12 ns performance. Ensure system voltage matches the 4.5 V to 5.5 V range. Consider package compatibility for through-hole assembly processes.

Part Context
