MC100EP016FAR2

Counter Dividers Overview

The MC100EP016FAR2 is a high-speed synchronous, presettable, cascadeable 8-bit binary up counter from the MC100EP016A series. It operates in PECL mode with VCC ranging from 3.0 V to 3.6 V (VEE = 0 V) or NECL mode with VEE from -3.0 V to -3.6 V (VCC = 0 V). The device features a typical propagation delay of 550 ps and supports operation frequencies exceeding 1.3 GHz. It includes an asynchronous master reset, internal terminal count feedback gated by the TCLD pin for programmable counting, and differential clock inputs. The component is housed in a QFN-32 package.

Counter Dividers Feature Summary

• Supports fully synchronous counting and generation of terminal count signals
• Features internal TC feedback gated by the TCLD pin for automatic reloading upon reaching an all-one state
• Includes safety clamps on clock inputs and open input default states
• Provides differential outputs via COUT and COUT pins

Counter Dividers Applications

• High-frequency binary counters
• Programmable frequency dividers
• Cascaded multi-bit counter chains
• Synchronous data processing systems

Counter Dividers Procurement Notes

Verify that the specific ordering suffix matches the required package type and shipping configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against the project specifications. Ensure the selected variant aligns with the necessary thermal management and lead-free soldering processes.

Counter Dividers Selection Notes

Select this component when high-speed synchronous counting with programmable reload capabilities is required. Consider the MC100EP016A series for applications needing operation frequencies above 1.3 GHz. Evaluate the QFN-32 package for thermal performance and board space constraints compared to alternative LQFP options.

Counter Dividers Part Context

This part belongs to the MC100EP016A family of ECL logic devices. It shares architectural similarities with the ECLinPS family but offers higher operating speeds. The device integrates 1226 transistors and meets JEDEC latchup test specifications. It is designed for robust performance in demanding high-speed digital environments.

Counter Dividers Replacement Considerations

Public confirmed substitute part numbers include MC100EP016AFAG and MC10EP016FAG.

Counter Dividers FAQ

How does the TCLD pin function affect the counting behavior?

When TCLD is HIGH, the internal TC feedback causes the counter to automatically reload the parallel data present at the Pn inputs upon reaching terminal count (all-ones state), enabling programmable division.

What is the recommended handling for unused Q outputs?

To minimize noise and power consumption, unused Q outputs should be left unterminated. Termination is only necessary for outputs actively used in the system.
