MC10EL58DT

Overview

The MC10EL58DT 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 on data and select inputs, ensuring stable logic states when pins are left open. It operates within a temperature range of -40°C to +85°C and is available in an 8-lead TSSOP package.

Feature Summary

• High-speed AC performance with propagation delay as low as 230 ps for ultimate signal integrity
• Internal pulldown resistors on all inputs simplify circuit design and improve noise immunity
• Dual-mode operation supporting both PECL and NECL power supply configurations
• ESD protection exceeding 1 kV human body model and 100 V machine model standards

Applications

• High-speed data acquisition systems requiring rapid signal selection
• Clock distribution networks demanding minimal propagation delay
• Telecommunications equipment utilizing ECL interface standards
• Test and measurement instruments needing precise timing control

Procurement Notes

Verify the specific ordering suffix DT indicates the TSSOP-8 package variant. Confirm RoHS compliance status as some older revisions may differ. Check current production status since certain variants in this family have been discontinued. Ensure proper termination techniques are applied to outputs to maintain signal integrity at high frequencies.

Selection Notes

Select the MC10EL58DT when superior AC performance over standard ECL devices is required. Choose this part if the application demands internal pulldown resistors to reduce external component count. Verify that the TSSOP-8 package fits the board layout constraints. Consider the 100EL series if temperature compensation is necessary for wide thermal variations.

Part Context

This component belongs to the MC10EL/100EL logic family designed for high-performance ECL applications. It serves as a direct replacement for legacy E158 multiplexers while providing enhanced speed characteristics. The device integrates four transistors into a compact surface-mount package suitable for dense PCB layouts.

Replacement Considerations

MC100EL58DTG is the temperature-compensated version of this device. MC10EL58DG offers the same functionality in an SOIC-8 package.
