MC10EP58DT

Overview

The MC10EP58DT is a high-speed 2:1 multiplexer from the onsemi 10EP series, designed for ECL logic applications. It operates with dual power supplies, supporting PECL mode (VCC 3.0V to 5.5V, VEE 0V) and NECL mode (VCC 0V, VEE -3.0V to -5.5V). The device features a typical propagation delay of 310 ps and supports maximum frequencies exceeding 3 GHz. It is housed in an 8-TSSOP surface-mount package and includes internal input pull-down resistors for signal stability.

Feature Summary

• High-speed data selection with low propagation delay suitable for demanding AC performance requirements
• Dual-mode operation compatibility with both PECL and NECL power supply configurations
• Integrated internal input pull-down resistors at data and select pins to reduce external circuit complexity
• Temperature-compensated design within the 100-series family for stable performance across operating ranges

Applications

• High-speed data communication systems requiring rapid signal routing
• Fast data acquisition circuits needing precise timing control
• ECL-based digital logic designs utilizing differential signaling

Procurement Notes

Verify the specific suffix against official documentation, as the MC10EP58DT designation may represent a variant or legacy part number. Confirm current manufacturing status, as related parts like MC10EP58DTG are marked obsolete. Ensure the selected component matches the required voltage levels and package type for your specific PCB layout and power architecture constraints.

Selection Notes

Select this component when designing systems that require fast switching between two ECL data sources. Consider the 100-series temperature compensation if operating in varying thermal environments. Verify that the power supply rails align with the specified PECL or NECL ranges. Check for direct replacements if the exact DT suffix is unavailable due to lifecycle changes.

Part Context

This device belongs to the onsemi MC10EP logic family, which provides high-performance ECL components. It functions similarly to the EL58 and LVEL58 devices but offers improved speed characteristics. The 10EP series is engineered for applications where minimal signal delay and high-frequency operation are critical for system integrity.

Replacement Considerations

The MC100EP58DTG is listed as a direct replacement for the MC10EP58DTG. Verify pinout and electrical specifications match before substitution. Other compatible parts include the MC10EL58 and MC100EL58, though these belong to different sub-families.
