SY100E136JC

Counter Dividers Overview

The SY100E136JC is a 6-bit synchronous, presettable universal counter manufactured by Microchip Technology. It operates within an extended VEE range of -4.2V to -5.5V and supports count frequencies up to 650 MHz. The device features fully synchronous up/down counting controlled by S1 and S2 pins, alongside an asynchronous Master Reset. It includes look-ahead-carry input (CLIN) and output (CLOUT) for cascading without external gating. Packaged in a 28-pin PLCC, it utilizes differential outputs.

Counter Dividers Feature Summary

• Supports fully synchronous up and down counting with parallel data preset capability
• Includes registered look-ahead-carry input and output for high-speed cascading
• Features asynchronous master reset that forces outputs low
• Provides differential Q outputs to minimize switching noise

Counter Dividers Applications

• Cascaded wide-bit counters
• Programmable frequency dividers
• Self-stopping counters

Counter Dividers Procurement Notes

Verify component authenticity through authorized channels as the part may be obsolete or discontinued. Confirm package integrity and pin alignment upon receipt. Ensure power supply voltages strictly adhere to the specified VEE range to prevent damage. Review the datasheet for specific handling precautions related to ECL logic families.

Counter Dividers Selection Notes

Select this component for applications requiring high-speed synchronous counting with minimal propagation delay impact during cascading. The registered carry-out architecture eliminates glitches common in gated designs. Consider the 28-pin PLCC package constraints and ensure compatibility with existing board layouts designed for J-leaded carriers.

Counter Dividers Part Context

This device belongs to the 100E series of ECL logic components. It serves as a universal counter alternative to previous generations like the H136, offering improved performance through registered carry signals. The SY10/100E136 family is designed for high-performance systems where speed and signal integrity are critical.

Counter Dividers Replacement Considerations

Consult official cross-reference tools for compatible alternatives. Verify functional equivalence regarding pinout, voltage levels, and timing parameters before substitution.
