MC10E155FNR2G

Overview

The MC10E155FNR2G is a 5V ECL 6-bit 2:1 multiplexer-latch integrated circuit manufactured by onsemi. It contains six independent 2:1 multiplexers followed by transparent latches with single-ended outputs. The device supports PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = -4.2 V to -5.7 V). Key electrical parameters include a maximum toggle frequency of 1100 MHz, a maximum propagation delay from D to output of 825 ps, and a maximum propagation delay from latch enable to output of 850 ps. It features asynchronous master reset, dual latch enables, and internal input 50 kΩ pulldown resistors.

Feature Summary

• Six independent 2:1 multiplexers with transparent latches and single-ended outputs
• Asynchronous Master Reset overrides all other controls to set Q outputs LOW
• Dual Latch Enables control data transparency based on SEL input state
• Internal 50 kΩ input pulldown resistors for stable logic levels

Applications

• High-speed digital signal routing in communication systems
• Data selection and buffering in ECL-based processing architectures
• Clock distribution networks requiring precise timing control

Procurement Notes

Verify the specific ordering suffix 'R2' corresponds to the tape and reel packaging configuration containing 500 units per reel. Confirm that the 'G' suffix indicates a lead-free package compliant with RoHS standards. Ensure the procurement channel sources genuine onsemi components to guarantee adherence to the specified JEDEC latchup test standards and moisture sensitivity level requirements.

Selection Notes

Select this component when designing circuits requiring high-speed data multiplexing within ECL logic families. The device is suitable for applications demanding low propagation delays and high toggle frequencies up to 1100 MHz. Consider the PECL or NECL operating modes based on the system power supply architecture. Verify that the 28-lead PLCC package fits the available PCB real estate and thermal management constraints.

Part Context

This part belongs to the MC10E/100E series of ECL logic devices produced by onsemi. The 10E series represents standard performance variants, while the 100E series includes temperature compensation. The MC10E155 specifically integrates multiplexer and latch functions into a single 28-lead plastic quad flatpack package, distinguishing it from standalone mux or latch ICs in the same family.

FAQ

How does the Master Reset function interact with the latch enables?

The Master Reset (MR) overrides all other controls, including the dual latch enables (LEN1, LEN2), to force the Q outputs LOW regardless of the multiplexer select input or data states.

What is the difference between PECL and NECL operating modes for this device?

In PECL mode, VCC ranges from 4.2 V to 5.7 V with VEE at 0 V. In NECL mode, VCC is at 0 V with VEE ranging from -4.2 V to -5.7 V. The internal circuitry adapts to these voltage configurations.
