SY10E122JY

Overview

The SY10E122JY is a 9-bit non-inverting buffer manufactured by Microchip Technology, housed in a 28-pin PLCC package. It operates within an extended VEE range of –4.2V to –5.5V and features a maximum propagation delay of 500ps. The device includes internal 75KΩ input pulldown resistors and maintains full compatibility with industry standard 10KH and 100K I/O levels.

Feature Summary

• Provides nine non-inverting buffers for high-performance ECL systems
• Includes internal 75KΩ input pulldown resistors
• Fully compatible with Motorola MC10E/100E122 specifications

Applications

• High-performance ECL system buffering
• Fan-out applications requiring non-inverted signal transmission

Procurement Notes

Verify the specific ordering suffix (e.g., JY) against current manufacturer documentation to confirm lead-free status and package marking details. Confirm availability as this component may be subject to discontinuation or limited stock constraints. Ensure environmental compliance requirements match the specific batch data sheet.

Selection Notes

Select this component when nine buffered outputs are required without inversion. Verify that the operating voltage aligns with the specified –4.2V to –5.5V range. Consider the 28-pin PLCC footprint for PCB layout compatibility. Check if the 500ps propagation delay meets the timing requirements of the target circuit design.

Part Context

This part belongs to the SY10/100E series of ECL logic devices produced by Micrel, now part of Microchip Technology. The series is designed for high-speed digital applications requiring low propagation delays and robust signal integrity in ECL environments.

Replacement Considerations

The SY10E122JY is fully compatible with the Motorola MC10E122. Verify pinout and electrical characteristics before substituting with other generic ECL buffers.
