MK2761ASLF

Overview

The MK2761ASLF is a clock/frequency synthesizer integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum frequency of 27MHz. The device features one circuit with CMOS outputs and accepts clock or crystal inputs. It is housed in a 16-SOIC package (0.154 inch width) and functions within an operating temperature range of 0°C to 70°C. The component has a 2:7 input-to-output ratio and includes a PLL with bypass capability.

Feature Summary

• Clock/Frequency Synthesizer IC with 27MHz maximum frequency
• CMOS output interface with clock/crystal input support
• 16-SOIC surface-mount package
• 4.5V to 5.5V supply voltage operation

Applications

• General-purpose clock generation for digital systems
• Frequency synthesis in embedded electronics

Procurement Notes

The MK2761ASLF is listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or existing stock, as new production from Renesas is discontinued. Check RoHS compliance status, which is noted as non-compliant in available records.

Selection Notes

Select this component only if legacy compatibility with 27MHz clock requirements and 5V logic levels is necessary. Ensure the design accommodates the 16-SOIC footprint and 0-70°C operating temperature range. Verify that CMOS output drive capabilities meet downstream load requirements.

Part Context

This part belongs to the MK2761 family of clock synthesizers. The 'ASLF' suffix typically denotes specific packaging or tape/reel variations compared to standard bulk packages, though exact suffix definitions require consulting the official datasheet. It is distinct from Renesas microcontroller lines such as the SH7266 or RL78 series.

Replacement Considerations

As the part is obsolete, direct substitutes are not publicly confirmed in the provided data. Designers should evaluate generic 27MHz clock generators or modern Renesas alternatives with compatible pinouts and electrical specifications.
