Overview
The SY10E016JY is an 8-bit synchronous binary up counter manufactured by Microchip Technology. It operates within the ECLinPS (10E) family and is housed in a 28-pin PLCC package. The device supports a minimum count frequency of 700 MHz with an extended VEE range from –4.2V to –5.5V. Key electrical characteristics include a maximum propagation delay of 1000 ps from CLK to Q/TC and internal 75KΩ input pulldown resistors. It features asynchronous master reset, parallel load capabilities, and fully synchronous counting logic.
Feature Summary
- Supports high-speed synchronous counting with a minimum frequency of 700 MHz
- Features internal gated terminal count feedback for programmable division
- Includes asynchronous master reset and parallel data preset inputs
- Fully compatible with industry standard 10KH and 100K I/O levels
Applications
- High-performance ECL system counters
- Cascaded multi-bit counter implementations
- Programmable frequency dividers
- Binary counting applications requiring fast transition times
Procurement Notes
Verify component authenticity through authorized Microchip channels. Confirm RoHS compliance status as the JY suffix indicates a Pb-Free package with a matte-Sn bar-line indicator. Ensure proper handling for moisture-sensitive devices during storage and assembly processes.
Selection Notes
Select this component for designs requiring high-frequency synchronous counting within the ECLinPS ecosystem. Consider the 28-pin PLCC package constraints and verify voltage compatibility with the extended VEE range. Evaluate cascading requirements if bit widths exceeding 8 bits are necessary.
Part Context
This part belongs to the SY10/100E016 series of 8-bit synchronous binary up counters. It shares architectural similarities with the Motorola MC10H016 but extends functionality for modern high-performance ECL systems. The product line emphasizes speed and compatibility with established MECL standards.
Replacement Considerations
The datasheet confirms full compatibility with the Motorola MC10E/100E016. Designers may consider these equivalents for pin-compatible replacements while verifying specific electrical parameter tolerances.
