MC10ELT20DT

Translators, Level Shifters Overview

The MC10ELT20DT is a single-gate TTL to differential PECL 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 features PNP TTL inputs for minimal loading and provides differential PECL outputs. Typical propagation delay ranges from 0.6 ns to 1.35 ns depending on temperature, with a maximum toggle frequency of 100 MHz. Power supply current is typically 16 mA. It is housed in an 8-lead TSSOP package (DT suffix) and meets RoHS standards.

Translators, Level Shifters Feature Summary

• Converts standard TTL logic levels to differential PECL signals using a single gate architecture.
• Utilizes PNP TTL input structure to minimize loading on the driving circuit.
• Includes internal ESD protection rated greater than 4 kV for human body model and greater than 200 V for machine model.
• Operates reliably across a wide industrial temperature range from -40°C to +85°C.

Translators, Level Shifters Applications

• Interfacing TTL-based digital systems with high-speed PECL clock distribution networks.
• Level translation in communication equipment requiring differential signaling.
• High-frequency data acquisition systems utilizing PECL receivers.

Translators, Level Shifters Procurement Notes

Verify that the specific part number matches the required package type, as the DT suffix indicates a TSSOP-8 package. Confirm compliance requirements such as RoHS status and lead-free specifications against project constraints. Ensure the operating voltage aligns with the specified 4.75 V to 5.25 V range. Check for any specific moisture sensitivity level requirements associated with the TSSOP packaging during storage and assembly.

Translators, Level Shifters Selection Notes

Select this component when interfacing 5V TTL sources with PECL destinations is required. Consider the MC100ELT20 variant if temperature compensation is necessary for stable performance across varying thermal conditions. Evaluate the power consumption of 16 mA against system budget constraints. Ensure the PCB layout supports the termination requirements for PECL outputs to maintain signal integrity at frequencies up to 100 MHz.

Translators, Level Shifters Part Context

This device belongs to the MC10EL/100EL series of ECL translators produced by onsemi. It serves as a bridge between standard TTL logic families and Positive ECL (PECL) circuits. The ELT20 specifically handles single-channel conversion, making it suitable for applications where space is limited but high-speed differential output is needed. It complements other devices in the family like the MC10ELT20DG which uses an SOIC-8 package.

Translators, Level Shifters FAQ

What is the function of the NC pins on the MC10ELT20DT?

The No Connect (NC) pins are internally unconnected and should be left floating or tied to ground for mechanical stability, but they do not affect the electrical operation of the translator.

How does the MC10ELT20 handle open inputs?

When the TTL input is left open, the output state is undetermined. However, the device includes internal pull-down resistors to help define the input state in certain configurations, though explicit termination is recommended for reliable operation.
