ON Semiconductor MC100ELT28D - Dual Differential PECL to TTL Translator

The MC100ELT28D is a versatile dual differential PECL (Positive Emitter Coupled Logic) to TTL (Transistor-Transistor Logic) translator device, designed by ON Semiconductor, a leading supplier of semiconductor-based solutions. This high-performance integrated circuit is specifically engineered to address the needs for converting PECL logic levels to TTL logic levels in digital systems.

Featuring a robust design, the MC100ELT28D operates over a wide voltage range and is capable of withstanding differential input voltages significantly above the supply voltage. This makes it an ideal choice for interfacing between systems operating at different logic levels, such as between high-speed networking equipment and traditional digital circuitry.

The device comes in a compact 8-pin SOIC package, which makes it suitable for space-constrained applications. The MC100ELT28D also offers a differential PECL input structure which provides an increased noise margin and improved signal integrity, especially beneficial in environments with high electromagnetic interference (EMI).

Key features of the MC100ELT28D include:

• Maximum rated PECL input to TTL output propagation delay of 4.5ns, ensuring fast signal translation for high-speed applications.
• Operating range from -40°C to 85°C, providing reliable performance across a broad range of environmental conditions.
• Integrated TTL output enable feature, allowing for additional flexibility in controlling the output states.
• Power supply range from 4.2V to 5.5V, compatible with standard TTL power supply levels.
• Asynchronous State Machine design, which minimizes setup and hold times.

The MC100ELT28D is widely used in various applications, including data communication, telecommunication, and computing systems where signal integrity and speed are critical. Its ability to provide reliable level translation with minimal propagation delay makes it an essential component in the interface design of modern electronic systems.

ON Semiconductor's commitment to high-quality and performance is reflected in the MC100ELT28D, making it a smart choice for designers looking for a reliable PECL to TTL translation solution.
