MC100ELT21DTR2G

Translators, Level Shifters Overview

The MC100ELT21DTR2G 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 delays of 5.5 ns across the operating temperature range of -40°C to +85°C. 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 is supplied in tape and reel packaging.

Translators, Level Shifters Feature Summary

• Converts differential PECL signals to standard TTL logic levels using only positive supply voltage
• Includes an internal reference voltage output (VBB) for AC coupling or unused input biasing
• Features flow-through pinout architecture to simplify printed circuit board layout
• Incorporates internal input pulldown resistors and ESD protection exceeding 2 kV human body model

Translators, Level Shifters Applications

• Interfacing high-speed PECL clock distribution networks with TTL-based digital logic
• Level translation in telecommunications equipment requiring low power consumption
• Data acquisition systems connecting differential signal sources to TTL receivers
• Space-constrained electronic designs utilizing single-gate translators

Translators, Level Shifters Procurement Notes

Verify that the specific part number corresponds to the TSSOP-8 package variant, as the SOIC-8 version utilizes a different suffix. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design requirements align with the specified 4.75 V to 5.25 V operating voltage range. Validate thermal management strategies against the junction-to-ambient resistance values provided in the datasheet for the selected mounting conditions.

Translators, Level Shifters Selection Notes

Select this component when interfacing PECL sources with TTL destinations in space-limited applications. The 100 Series designation indicates the inclusion of temperature compensation for enhanced performance stability across varying environmental conditions. Consider the 100 MHz maximum toggle frequency and 3.5 ns typical delay for high-speed timing requirements. Evaluate the need for the VBB reference pin functionality if AC coupling or unused differential inputs are present in the circuit design.

Translators, Level Shifters Part Context

This device belongs to the MC100ELT21 family of ECLinPS logic components designed for high-speed digital applications. The product line emphasizes low power consumption and small form factors suitable for dense circuit layouts. The MC100 prefix specifically denotes the inclusion of temperature-compensated characteristics, distinguishing it from the standard MC10 series which lacks this feature.

Translators, Level Shifters Replacement Considerations

MC10ELT21DTR2G: Functionally equivalent single-gate PECL to TTL translator; differs only by the absence of temperature compensation features found in the 100 series.
