MC100EL58DT

Overview

The MC100EL58DT is a 2:1 multiplexer from the 100 Series, functionally equivalent to the E158 device but offering significantly faster propagation delays and output transition times. It features temperature compensation for stable performance across varying thermal conditions. The device 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). Key electrical parameters include a typical propagation delay of 230 ps, a maximum toggle frequency of 1.5 GHz, and a power supply current of 16 mA to 19 mA depending on temperature.

Feature Summary

• Temperature compensated design ensures consistent AC performance across operating temperatures.
• Internal input pulldown resistors on data and select pins simplify circuit design and improve signal stability.
• High-speed operation suitable for applications requiring ultimate AC performance.
• ESD protection exceeds 1 kV human body model and 100 V machine model standards.

Applications

• High-speed data transmission systems
• Clock distribution networks
• Signal routing in high-frequency communication equipment

Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-8 package configuration required for your PCB layout. Confirm RoHS compliance status as manufacturing processes may evolve. Check for discontinuation notices or recommended replacement parts via official onsemi channels before finalizing procurement plans.

Selection Notes

Select this component when temperature stability is critical for maintaining signal integrity in high-speed ECL logic circuits. Ensure the design accommodates the specified dual-supply voltage ranges for either PECL or NECL operation. Verify that the TSSOP-8 package dimensions fit within the available board space constraints.

Part Context

This device belongs to the MC10EL/100EL series of ECL logic components manufactured by onsemi. The 100 Series designation indicates the inclusion of internal temperature compensation, distinguishing it from the standard 10 Series which lacks this feature. It serves as a direct functional upgrade to legacy E158 devices.

Replacement Considerations

MC10EL58DTG is a compatible alternative within the same family.
