MC10EP016FAR2G

Counter Dividers Overview

The MC10EP016FAR2G is a high-speed, synchronous, presettable, cascadeable 8-bit binary up counter from onsemi. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE from -3.0 V to -5.5 V (VCC = 0 V). The device features a typical propagation delay of 500 ps and supports a maximum counting frequency exceeding 1 GHz for Q outputs. It includes internal TC feedback gated by the TCLD pin for programmable division, differential clock inputs, and an asynchronous master reset. Packaged in a lead-free LQFP-32.

Counter Dividers Feature Summary

• Supports both PECL and NECL operating voltage ranges for flexible power supply integration.
• Features internal terminal count feedback gated by the TCLD pin to enable automatic reloading as a programmable counter.
• Includes differential clock inputs and dedicated COUT/COUTB outputs for single non-cascaded applications.
• Provides fully synchronous counting and generation of terminal count signals alongside an asynchronous master reset.

Counter Dividers Applications

• High-frequency binary counting and frequency division
• Programmable divider circuits utilizing internal TC feedback
• Cascaded multi-bit counter chains requiring external gating

Counter Dividers Procurement Notes

Verify that the specific ordering suffix 'R2G' corresponds to the Tape & Reel packaging configuration containing 2,000 units per reel. Confirm that the assembly location code 'A' matches the required manufacturing site qualification. Ensure the Pb-Free package designation aligns with environmental compliance requirements for the target application.

Counter Dividers Selection Notes

Select this component when a synchronous 8-bit ECL counter with internal programmable reload capability is required. It is suitable for designs needing differential clock inputs and operation within standard PECL or NECL voltage domains. Consider cascading multiple units for wider bit widths, noting that external OR gates are necessary for counters exceeding 16 bits.

Counter Dividers Part Context

This part belongs to the 10EP series of ECL logic devices manufactured by onsemi. It shares architectural similarities with the MC10E016 from the ECLinPS family but is optimized for standalone ECL operation. The device is designed for high-speed digital systems requiring precise timing control and low jitter performance in binary counting applications.

Counter Dividers Replacement Considerations

MC10EP016FAG is a parameter-equivalent alternative available in Tray packaging.

Counter Dividers FAQ

How does the TCLD pin function affect the counting behavior?

When TCLD is HIGH, internal TC feedback causes the counter to automatically reload the parallel data upon reaching terminal count. When LOW or open, counting proceeds continuously without reloading.

Can the COUT and COUTB outputs be used in a cascade chain?

No, COUT and COUTB should not be used in cascade configurations. Only the TC output should be used for connecting multiple EP016 devices in a counter or divider chain.
