• Low propagation delay
• Differential input provides noise immunity
• Wide operating temperature range

Disadvantages

• Requires external power supply
• Limited to translating ECL to TTL signals only

Working Principles

The MC100ELT22DTR2G is designed to translate ECL logic signals to TTL levels. It operates by receiving a differential ECL input signal on pins D and /D, which is then processed internally to generate complementary TTL output signals on pins Q and /Q. The device requires an external power supply within the specified voltage range to function properly.

Detailed Application Field Plans

The MC100ELT22DTR2G can be used in various applications that require the translation of high-speed ECL signals to TTL levels. Some potential application fields include:

1. Telecommunications: Signal translation between ECL-based communication systems and TTL-based devices.
2. Data Communication: Interface conversion between ECL data transmission systems and TTL-compatible equipment.
3. Industrial Automation: Integration of ECL-based control systems with TTL logic circuits.
4. Test and Measurement: Signal conditioning and level shifting in high-speed test setups involving both ECL and TTL components.

Detailed and Complete Alternative Models

1. MC10ELT22: Similar functionality, but available in a different package (SOIC-8).
2. MC100ELT21: Single-ended version of the MC100ELT22DTR2G, suitable for non-differential input applications.
3. MC100LVELT22: Compatible alternative from the LVEL (Low-Voltage Emitter-Coupled Logic) series, designed for lower voltage operation.

These alternative models provide similar functionality and can be considered as substitutes for the MC100ELT22DTR2G depending on specific requirements and constraints.
