SY10E016JY-TR

Overview

The SY10E016JY-TR is an 8-bit synchronous binary up counter from the ECLinPS 10E series, manufactured by Microchip Technology. It operates within an extended VEE range of –4.2V to –5.5V and supports a minimum count frequency of 700MHz. The device features fully synchronous counting, parallel preset inputs (P0-P7), asynchronous master reset, and cascadable terminal count outputs. Packaged in a lead-free 28-pin PLCC (J28-1) with matte tin finish, it includes internal 75KΩ input pulldown resistors and maintains compatibility with industry-standard 10KH and 100K I/O levels.

Feature Summary

• High-speed synchronous 8-bit binary counting architecture designed for high-performance ECL systems
• Internal gated TC feedback mechanism enabling programmable counter functionality via TCLD pin
• Fully compatible with Motorola MC10E/100E016 logic levels and standard ECL interfaces
• Asynchronous master reset and parallel load capabilities for flexible state control

Applications

• Cascading multiple devices to construct wide-bit counters exceeding 8 bits
• Implementing programmable frequency dividers using internal terminal count reload
• High-frequency digital timing and sequencing circuits requiring precise clock synchronization

Procurement Notes

Verify that the ordering suffix JY corresponds to the industrial temperature range and the specific lead-free package configuration. Confirm that the TR suffix indicates tape and reel packaging as documented in the official ordering information table. Ensure compliance with RoHS standards if required by the design specifications.

Selection Notes

Select this component when designing systems requiring high-speed synchronous counting within the ECLinPS 10E family. Consider the 700MHz minimum count frequency and the availability of parallel preset inputs for applications demanding rapid state initialization. Evaluate the need for cascadability if bit widths larger than 8 bits are required.

Part Context

This part belongs to the Micrel SY10/100E016 family of high-speed synchronous binary counters. It shares architectural similarities with the Motorola MC10H016 but extends functionality to 8 bits. The device is optimized for new high-performance ECL systems, offering extended voltage ranges and internal feedback mechanisms not present in older generations.

Replacement Considerations

The SY100E016 serves as a direct functional substitute within the same family, differing primarily in operating speed characteristics. Verify pinout compatibility and electrical parameter alignment before substitution.
