MC100LVEL58DTG

Overview

The MC100LVEL58DTG is a 2:1 multiplexer from the MC100LVEL series, designed for high-speed signal routing in low-voltage ECL applications. It operates with dual power supplies ranging from ±3V to ±3.8V. The device features a propagation delay of 600 ps and supports data rates suitable for demanding digital systems. Packaged in an 8-pin TSSOP surface-mount format, it includes internal pull-down resistors on data and select inputs to ensure defined states during idle conditions.

Feature Summary

• Supports wide supply voltage ranges compatible with both PECL and NECL logic families
• Includes internal input pull-down resistors to stabilize signal states without external components
• Temperature-compensated design ensures stable performance across industrial operating temperatures

Applications

• High-speed data acquisition systems requiring fast signal selection
• Telecommunications equipment utilizing LVPECL signaling standards
• Test and measurement instruments needing precise multiplexing capabilities

Procurement Notes

Verify the specific suffix DTG confirms the TSSOP-8 package and tape-and-reel shipping configuration. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Ensure the design accommodates the ±3V to ±3.8V dual supply requirement rather than single-supply configurations typical of other logic families.

Selection Notes

Select this component when interfacing between different ECL voltage domains or when low skew multiplexing is required. Compare against the MC10EL58DG for standard ECL voltages if higher supply rails are available. Consider the MC100EP58 for broader voltage compatibility spanning 3.3V and 5V systems.

Part Context

This part belongs to the MC100LVEL family of low-voltage ECL multiplexers. It serves as a functional equivalent to older ECL devices but offers improved speed and lower power consumption. The 100-series designation indicates temperature compensation features integrated into the silicon design for consistent timing characteristics.

Replacement Considerations

The MC100LVEL58DG is a pin-compatible alternative in tube packaging. For obsolete stock, Rochester Electronics may supply similar variants. Verify that any substitute maintains the same 600 ps propagation delay and ±3.8V maximum supply rating.
