83904AG-02LFT

Overview

The 83904AG-02LFT is a clock fan-out buffer and multiplexer manufactured by Renesas Electronics Corporation. It features a 3:4 input-to-output ratio with a maximum operating frequency of 200 MHz. The device supports LVCMOS and LVTTL output logic levels and accepts LVCMOS, LVTTL, or crystal inputs. It operates within a supply voltage range of 2.375V to 3.465V and is housed in a 16-TSSOP package (0.173 inch / 4.40mm width). The component is rated for an industrial temperature range of 0°C to 70°C.

Feature Summary

• 3:4 Fan-Out Buffer and Multiplexer Configuration
• Maximum Frequency of 200 MHz
• LVCMOS/LVTTL Output Support
• 16-TSSOP Surface Mount Package

Applications

• Clock distribution networks requiring signal buffering
• System synchronization circuits
• Digital logic interface timing management

Procurement Notes

The 83904AG-02LF variant is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or existing stock rather than direct manufacturing orders. Confirm RoHS3 compliance status and check for specific lot date codes when sourcing from secondary markets.

Selection Notes

Designers must account for the discontinued status of this part number during new product development. Verify that the 200 MHz frequency limit meets system requirements. Ensure the 2.375V to 3.465V supply voltage aligns with the target platform's power rails. The 16-TSSOP footprint requires appropriate PCB layout considerations for thermal dissipation and signal integrity.

Part Context

This component belongs to the 83904A family of clock buffers. It serves as a specialized timing solution for distributing clock signals across digital systems. The 'LF' suffix indicates lead-free construction, and the 'T' suffix typically denotes tape-and-reel packaging, though official documentation confirms tube packaging for the base part.

Replacement Considerations

As the part is obsolete, no direct public substitute is confirmed in the provided data. Engineers should evaluate current Renesas clock buffer families or third-party equivalents with matching 3:4 ratios, 200 MHz speed, and 16-TSSOP packages.
