SY89322VMI-TR

Translators, Level Shifters Overview

The SY89322VMI-TR is a dual TTL/CMOS-to-differential PECL translator manufactured by Microchip Technology. It operates from a single +3.3V or +5V supply without requiring a negative voltage. The device features PNP LVTTL inputs for minimal loading and provides differential LVPECL outputs that default to LOW when inputs are open. It supports a maximum toggle frequency of 800MHz with a typical propagation delay of 300ps. The component is housed in an ultra-small 8-pin MLF® (2mm x 2mm) package.

Translators, Level Shifters Feature Summary

• Dual channel translation between TTL/CMOS/LVTTL/LVCMOS inputs and differential LVPECL outputs
• Operates on a single positive power supply, eliminating the need for negative voltages
• Utilizes PNP input structures to minimize loading effects on driving circuits
• Outputs default to a HIGH state if inputs remain unconnected

Translators, Level Shifters Applications

• LVTTL/LVCMOS to LVPECL system interfacing
• TTL/CMOS to PECL system interfacing
• Space-constrained high-speed digital designs

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm lead finish and RoHS compliance status. Confirm the manufacturer origin, as this part was originally developed by Micrel before acquisition. Ensure the package marking matches the industrial operating temperature range specifications provided in the datasheet.

Translators, Level Shifters Selection Notes

Select this component for applications requiring low skew and low power consumption within a minimal footprint. It serves as a functional equivalent to the SY100EPT22V but offers a significantly smaller package size. Ensure the design accommodates the exposed pad requirement for proper thermal management and ground connection.

Translators, Level Shifters Part Context

This component belongs to the Precision Edge family of high-speed logic devices. Originally produced by Micrel, Inc., it is now distributed under the Microchip Technology brand. The device is designed to bridge different logic families while maintaining signal integrity at high frequencies.

Translators, Level Shifters Replacement Considerations

The SY89322V is functionally equivalent to the SY100EPT22V. Verify pinout compatibility and package dimensions when substituting.
