MC10EL58D

Overview

The MC10EL58D is a 2:1 multiplexer from the onsemi 10EL series, functionally equivalent to the E158 device but offering significantly faster propagation delays and output transition times. It supports PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) and NECL mode with VEE ranging from -4.2 V to -5.7 V (VCC = 0 V). The device features internal input pulldown resistors of 75 kΩ on data and select inputs, ensuring stable operation when pins are left open. It operates within a temperature range of -40°C to +85°C and includes ESD protection exceeding 1 kV (HBM) and 100 V (MM).

Feature Summary

• High-speed AC performance with propagation delay as low as 230 ps.
• Internal 75 kΩ pulldown resistors on all inputs for signal stability.
• Wide operating voltage support for both PECL and NECL logic families.
• ESD protection rated above 1 kV Human Body Model and 100 V Machine Model.

Applications

• High-frequency communication systems requiring fast signal selection.
• Data acquisition systems needing rapid multiplexing capabilities.
• AC-coupled interfaces utilizing differential ECL signaling.

Procurement Notes

Verify the specific suffix against current availability, as some variants like MC10EL58DG are discontinued. Confirm package type matches design requirements, such as SOIC-8 or TSSOP-8. Ensure RoHS compliance documentation is obtained if required by project specifications. Check for lead-free status and halogen-free material declarations prior to ordering.

Selection Notes

Select this component for applications demanding superior AC performance compared to standard ECL devices. Choose the 10EL series for general high-speed needs or the 100EL series if temperature compensation is required. Ensure power supply configurations align with either PECL or NECL standards. Verify that the 8-pin package fits the PCB layout constraints.

Part Context

This device belongs to the MC10EL/100EL family of high-performance ECL logic components. It serves as an upgraded alternative to the legacy E158 multiplexer, providing enhanced speed characteristics while maintaining functional compatibility. The part is designed for integration into complex digital systems where signal integrity and timing precision are critical.

Replacement Considerations

The MC100EL58 offers similar functionality with added temperature compensation features. Standard E158 devices are functionally equivalent but exhibit slower propagation delays. Designers should verify pinout compatibility and electrical parameter differences when substituting these parts in existing circuits.

FAQ

What happens if the SEL input is left unconnected?

The internal 75 kΩ pulldown resistor ensures the SEL pin defaults to a low state, selecting Data Input B.

Does this device include temperature compensation?

No, the MC10EL58 does not include temperature compensation; this feature is available only in the MC100EL58 variant.
