MC10ELT21DTG

Translators, Level Shifters Overview

The MC10ELT21DTG is a single-gate differential PECL to TTL translator manufactured by onsemi. It operates with a +5 V supply and ground, utilizing an internally generated VBB reference voltage for input biasing. The device features a TSSOP-8 surface-mount package and provides flow-through pinouts. Key electrical parameters include a typical propagation delay of 3.5 ns, a maximum toggle frequency of 100 MHz, and a TTL output capable of sourcing -3 mA and sinking 24 mA. It functions within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Converts differential PECL signals to standard TTL logic levels using a single gate architecture.
• Includes an internal VBB reference voltage output to simplify AC coupling and biasing requirements.
• Features a Q output that defaults to LOW when inputs are left open or below 1.3 V.
• Designed for space-constrained applications requiring low power consumption and high performance.

Translators, Level Shifters Applications

• Interfacing PECL clock sources with TTL-based digital systems
• High-speed data translation in telecommunications equipment
• Signal conversion in test and measurement instrumentation

Translators, Level Shifters Procurement Notes

Verify the specific suffix DTG confirms the TSSOP-8 package and Pb-free compliance as documented in the ordering information. Ensure the design accounts for the VBB pin current limits of ±0.5 mA if utilized for decoupling or biasing. Confirm the operating voltage range matches the required 4.75 V to 5.25 V specification for proper signal integrity.

Translators, Level Shifters Selection Notes

Select this component when interfacing PECL outputs directly to TTL inputs without external level shifting circuits. The single-gate configuration reduces board space compared to dual-gate alternatives. Consider the 100 Series variant (MC100ELT21) if temperature compensation is explicitly required for the application environment.

Translators, Level Shifters Part Context

This part belongs to the MC10ELT/100ELT21 family of ECLinPS translators. It is designed to bridge the gap between Positive ECL logic families and standard TTL interfaces. The device is part of onsemi's portfolio focused on high-speed signal conditioning and interface solutions for industrial and communication systems.

Translators, Level Shifters Replacement Considerations

The MC100ELT21DTG serves as a direct functional substitute within the same package, offering temperature-compensated characteristics. Other devices in the MC10ELT series may provide similar functionality but require verification of package compatibility and specific electrical parameter alignment.
