MC10ELT21DG

Translators, Level Shifters Overview

The MC10ELT21DG is a 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 features a typical propagation delay of 3.5 ns and provides a 24 mA TTL output capability. It utilizes a small outline 8-lead package for space-efficient designs. The component includes an internally generated voltage supply pin (VBB) for single-ended input conditions or AC coupling rebiasing, requiring decoupling via a 0.01 μF capacitor when active.

Translators, Level Shifters Feature Summary

• Converts differential PECL signals to TTL levels using only positive supply and ground connections.
• Includes an internal voltage reference pin (VBB) to support single-ended inputs or AC-coupled signal biasing.
• Outputs default to LOW state if inputs are left open or fall below the specified threshold voltage.

Translators, Level Shifters Applications

• High-performance systems requiring compact logic translation between PECL and TTL domains.
• Applications prioritizing low power consumption alongside high-speed signal processing.
• Space-constrained circuit designs utilizing the small outline 8-lead package format.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DG' corresponds to the lead-free, halogen-free, and RoHS-compliant variant as documented in official datasheets. Confirm that the operating environment remains within the specified 4.75 V to 5.25 V supply range to ensure correct logic level translation and signal integrity. Ensure proper decoupling of the VBB pin if utilized for single-ended inputs.

Translators, Level Shifters Selection Notes

Select this component when interfacing PECL sources with TTL destinations in environments where power efficiency and physical footprint are critical constraints. The inclusion of the VBB pin offers flexibility for managing single-ended inputs without external biasing networks. Consider the 3.5 ns propagation delay against system timing requirements to validate suitability for the target data rates.
