MC10E157FNR2

Overview

The MC10E157FNR2 is a 5 V ECL Quad 2:1 Multiplexer manufactured by onsemi. It contains four independent multiplexers with differential outputs controlled by individual Select (SEL) inputs. 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 propagation delay of 550 ps from data input to output and 800 ps from select input to output. It operates within a temperature range of 0°C to +85°C and features internal 50 kΩ input pulldown resistors.

Feature Summary

• Features four independent 2:1 multiplexers with differential outputs for random logic designs.
• Includes internal 50 kΩ input pulldown resistors to stabilize input signals.
• Provides robust electrostatic discharge protection exceeding specified Human Body Model and Machine Model thresholds.
• Supports both PECL and NECL operating voltage configurations.

Applications

• Random logic circuit designs requiring independent channel selection
• High-speed signal routing in communication systems
• Data path switching in processing architectures

Procurement Notes

Verify the specific ordering suffix to confirm package type and environmental compliance. The FNR2 suffix indicates a Tape & Reel packaging format. Confirm RoHS status and moisture sensitivity level requirements against project specifications before procurement. Ensure compatibility with existing supply chain channels for this component series.

Selection Notes

Select this component when designing circuits requiring multiple independent 2:1 multiplexing functions within a single package. Consider the MC100E157 variant if temperature compensation is required for stable performance across varying thermal conditions. Evaluate power supply constraints to ensure alignment with either PECL or NECL operational modes.

Part Context

This device belongs to the MC10E/100E family of high-speed emitter-coupled logic components. It is housed in a 28-lead PLCC package. The 10E series represents standard performance levels, while the 100E series includes additional temperature compensation features. This specific part number denotes the non-temperature-compensated version in reel packaging.

Replacement Considerations

The MC100E157 serves as a direct functional substitute offering temperature compensation. Other members of the MC10E/100E logic family may provide alternative pinouts or functionalities but require careful verification of electrical characteristics and interface compatibility.
