SY100E122JC

Overview

The SY100E122JC is a 9-bit non-inverting buffer from the 100E series, designed for high-performance ECL systems. It operates within an extended VEE range of –4.2V to –5.5V and features internal 75KΩ input pulldown resistors. The device provides nine data inputs (D0-D8) and corresponding outputs (Q0-Q8). Key electrical specifications include a maximum propagation delay of 500ps, typical rise/fall times of 425ps, and within-device skew of 75ps. Power supply current typically ranges from 41mA to 49mA.

Feature Summary

• Provides nine non-inverting buffers for signal distribution in ECL architectures
• Features internal 75KΩ input pull-down resistors for stable logic levels
• Compatible with industry standard 10KH and 100K I/O voltage levels

Applications

• High-performance ECL system buffering
• Data bus driving applications requiring multiple fan-out
• Signal integrity maintenance in differential logic circuits

Procurement Notes

Verify component authenticity through authorized Microchip Technology channels or certified distributors. Confirm RoHS compliance status and package marking details against official datasheet specifications. Ensure ordering suffixes match required temperature ranges and packaging formats. Validate lead times and availability directly with suppliers prior to procurement commitment.

Selection Notes

Select this component when nine buffered outputs are required for ECL logic families. Consider the 28-pin PLCC package constraint for PCB layout. Evaluate power consumption requirements against the specified supply current range. Verify compatibility with existing 100K level interfaces if interfacing with legacy components.

Part Context

Part of the Micrel 100E series of high-speed ECL logic devices. Manufactured by Micrel, Inc., now part of Microchip Technology. Designed for commercial temperature ranges with specific voltage tolerances suitable for advanced telecommunications and computing infrastructure applications.

Replacement Considerations

Fully compatible with Motorola MC10E/100E122 equivalents. Check for pin-compatible alternatives within the same 100E family if volume or package variations are needed.
