83904AG-02LF

Overview

The Renesas 83904AG-02LF is a clock buffer and multiplexer IC designed for signal distribution. It features a 3:4 input-to-output ratio with a maximum operating frequency of 200 MHz. The device supports LVCMOS, LVTTL, and crystal inputs, providing LVCMOS or LVTTL outputs. It operates within a supply voltage range of 2.375 V to 3.465 V and functions at temperatures between 0°C and 70°C. Housed in a 16-TSSOP package (4.40 mm wide), this component is currently classified as obsolete by the manufacturer.

Feature Summary

• Clock fan-out buffer and multiplexer with 3:4 input/output ratio
• Maximum frequency operation up to 200 MHz
• Supports LVCMOS, LVTTL, and crystal input signals
• Single circuit configuration in a 16-TSSOP surface-mount package

Applications

• General-purpose clock signal distribution in digital systems
• Multiplexing multiple clock sources for system timing
• Embedded electronics requiring low-voltage CMOS/TTL clock buffering

Procurement Notes

This product has been officially declared End-of-Life (EOL) by Renesas Electronics Corporation, with the EOL notification dated March 1, 2019. Current availability is limited to existing stock from distributors; new production units are not manufactured. Buyers should verify the specific revision level and packaging type against legacy inventory records before procurement.

Selection Notes

Designers must account for the obsolete status when selecting this component for new hardware. Verify that the 2.375 V to 3.465 V supply voltage range aligns with the target system's power rails. Ensure the 16-TSSOP footprint matches the PCB layout constraints. Consider migrating to a current-generation Renesas clock buffer if long-term supply stability is required.

Part Context

The 83904AG-02LF belongs to the 83904A family of clock buffers. It serves as a specialized solution for distributing clock signals in applications requiring precise timing and signal integrity. As an obsolete part, it represents previous generation technology in Renesas' timing portfolio, often replaced by newer series with enhanced features or broader supply chains.

Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Users should consult Renesas migration guides or distributor cross-reference tools to identify compatible modern alternatives.
