MC100E158FNR2

Overview

The MC100E158FNR2 is a high-speed 5-bit 2:1 multiplexer manufactured by onsemi, belonging to the MC100E series. It operates with a single negative supply voltage ranging from -4.94V to -5.46V. The device is housed in a 20-PLCC (J-Lead) surface-mount package and supports an operating temperature range of 0°C to 75°C. This component functions as a signal selector within differential ECL logic circuits.

Feature Summary

• Provides 5-bit parallel data selection between two input sources using a single control line
• Designed for high-frequency operation utilizing standard ECL logic levels
• Integrated into a compact 20-pin plastic leaded chip carrier package for surface mounting

Applications

• High-speed digital signal routing systems
• Differential ECL logic circuit design
• Data acquisition and switching networks

Procurement Notes

Verify current availability status as this part number may be obsolete or subject to discontinuation notices. Confirm that the specific ordering suffix matches the required tape and reel packaging configuration. Ensure compatibility with existing -5V ECL power supplies and thermal management requirements for the PLCC package before finalizing procurement orders.

Selection Notes

Select this component when a 5-bit wide multiplexing function is required within a 5V ECL environment. Compare against the MC10E158 variant if different pinout configurations or commercial temperature ranges are acceptable. Verify that the 20-PLCC footprint aligns with the target PCB layout constraints and that the differential output characteristics meet system noise immunity standards.

Part Context

This device belongs to the MC100E family of high-performance ECL integrated circuits. It serves as a functional equivalent to older E158 specifications but offers improved AC performance metrics. The component is distinct from quad multiplexers like the MC10E157 and provides a dedicated solution for five-channel data selection tasks in legacy or specialized high-speed communication hardware.

Replacement Considerations

Public confirmed substitute part numbers include MC10E158FN, MC10E158FNG, and MC10E158FNR2. These alternatives share identical logical functionality and pinouts but may differ in package style or manufacturing revision. Verify electrical parameter tolerances and moisture sensitivity levels before substituting.
