MC10ELT21DTR2

Translators, Level Shifters Overview

The MC10ELT21DTR2 is a single-gate differential PECL to TTL translator manufactured by onsemi. It operates within a VCC range of 4.75 V to 5.25 V with GND at 0 V. The device features a typical propagation delay of 3.5 ns, with maximum limits of 5.5 ns. It provides a 24 mA TTL output drive capability and supports a maximum toggle frequency of 100 MHz. The component is housed in an 8-lead TSSOP package (DT suffix) and functions across an operating 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 configuration
• Includes an internally generated VBB reference voltage pin for AC coupling or single-ended input biasing
• Features flow-through pinouts compatible with standard ECL logic families

Translators, Level Shifters Applications

• Interfacing high-speed PECL clock distribution networks with TTL-based digital logic
• Level translation in telecommunications equipment requiring differential signal reception
• Test and measurement instrumentation utilizing mixed-signal logic interfaces

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'DTR2G' corresponds to the TSSOP-8 tape and reel packaging format as defined in the manufacturer's ordering information. Confirm that the RoHS compliance status matches current regulatory requirements for the intended deployment region. Ensure the procurement channel sources genuine components from authorized distributors to maintain reliability standards.

Translators, Level Shifters Selection Notes

Select this component when interfacing PECL sources with TTL loads in space-constrained designs. The TSSOP-8 package offers a compact footprint suitable for dense PCB layouts. Consider the 100 Series variant if temperature compensation is required for wider thermal stability, although the base model supports standard industrial temperatures.

Translators, Level Shifters Part Context

This part belongs to the MC10ELT/100ELT series of 5 V differential translators. It is designed for applications prioritizing low power consumption and small physical size. The device utilizes an 81-transistor count architecture within a plastic SOIC or TSSOP housing, providing a robust solution for converting Positive ECL levels to TTL without requiring negative supply voltages.
