MC10ELT21DT

Translators, Level Shifters Overview

The MC10ELT21DT is a single-gate differential PECL to TTL translator manufactured by onsemi. It operates within a supply voltage range of 4.75 V to 5.25 V with ground at 0 V. The device provides a typical propagation delay of 3.5 ns and supports a maximum toggle frequency of 100 MHz. It features a 24 mA TTL output capability and includes an internally generated reference voltage (VBB) for input biasing. The component is housed in an 8-lead TSSOP package and functions across an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Translates differential PECL signals to standard TTL logic levels using only positive power supply and ground connections.
• Includes an internal VBB pin that generates a reference voltage, allowing unused differential inputs to be connected as switching references or used to rebias AC-coupled inputs.
• Provides high drive strength with a 24 mA TTL output current capability.

Translators, Level Shifters Applications

• Interfacing high-speed PECL clock distribution networks with TTL-based digital logic circuits.
• Converting differential PECL data streams for processing by TTL-compatible receivers.
• Space-constrained designs requiring low-power translation between ECL-family and TTL families.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-8 package variant when ordering. Confirm RoHS compliance status for the specific manufacturing lot, as historical documentation indicates lead-free packaging. Ensure the design accounts for the moisture sensitivity level associated with the TSSOP-8 package type during storage and soldering processes.

Translators, Level Shifters Selection Notes

Select this component when interfacing PECL sources with TTL destinations in a single-channel configuration. The TSSOP-8 package is suitable for applications prioritizing board space efficiency over the SOIC-8 alternative. Designers must account for the internal VBB pin requirements if utilizing single-ended inputs or AC coupling, ensuring proper decoupling and current limiting are implemented in the circuit layout.

Translators, Level Shifters Part Context

This device belongs to the MC10EL/100EL family of high-speed ECL translators. While the 100 series incorporates temperature compensation, the base MC10ELT21 model provides essential translation functionality without this specific feature. It serves as a bridge component in mixed-voltage systems, enabling compatibility between Positive ECL standards and traditional Transistor-Transistor Logic interfaces.
