Today, we're going to dive into Emitter Coupled Logic, or ECL. Who knows what makes ECL stand out compared to other logic families?
I think it's because it's really fast, right?
Absolutely! ECL is known for its speed. It uses differential signaling to achieve high-speed operation. Can anyone tell me the first series of devices introduced for ECL?
Was it the MECL-I series?
Correct! The MECL-I series debuted in 1962. Let's remember this as a key milestone in the history of logic families.
What about MECL-II? Was that also significant?
Yes, the MECL-II series followed in 1966 and is notable for enhancing the initial design. However, both series have become obsolete now.
To wrap up, remember that ECL is notable for its high speed, an essential aspect in high-performance applications.

Now let's explore the current ECL subfamilies. Who can name one?
Is it the MECL-10K series?
Exactly right! The MECL-10K series is critical for various logic functions. Can anyone tell me what makes MECL-10H special?
I think itβs designed for higher speeds and lower power usage?
Precisely! Higher speeds with low power consumption are pivotal for modern applications, especially in portable devices.
What about MECL-10E? How does it compare?
Great question! The MECL-10E series introduces ECLinPS variants designed for both low and high-power operations, enhancing versatility. Let's remember the ECLinPS as a linchpin for efficient digital integration.
To sum up today's lesson, ECL is critical in the digital circuits landscape with its modern subfamilies such as MECL-10K, MECL-10H, and MECL-10E.

Quick Overview
Standard
Emitter Coupled Logic (ECL) is a high-speed logic family known for its quick response times. The section discusses the original MECL-I and MECL-II series, which have become obsolete, and focuses on popular modern subfamilies such as MECL-III, MECL-10K, MECL-10H, and MECL-10E, emphasizing their respective characteristics and applications in digital circuits.
Detailed
ECL Subfamilies
Emitter Coupled Logic (ECL) represents one of the fastest logic families available, often utilized in high-performance computing and data transmission systems. Initially, the MECL-I series was introduced by ON Semiconductor in 1962, followed by the MECL-II series in 1966, both of which have since been rendered obsolete. Today's significant subfamilies of ECL logic include:
- MECL-III (or MC1600 series): Similarly known as the third-generation ECL logic, designed to improve performance and reduce power consumption.
- MECL-10K series: This series is distinguished by its wide range of logic functions and adaptability for various applications.
- MECL-10H series: Characteristics include higher speeds and lower power, suitable for battery-powered applications.
- MECL-10E series: Part of the enhanced ECL series designed for both low and high-power operations with the introduction of ECLinPS (ECL in Plastic Surface Mount) and ECLinPSLite variants.
These ECL variations emphasize speed and efficiency in data handling, showcasing compatibility and versatility within the ecosystem of digital integrated circuits.

The first monolithic emitter coupled logic family was introduced by ON Semiconductor, formerly a division of Motorola, with the MECL-I series of devices in 1962, with the MECL-II series following it up in 1966. Both these logic families have become obsolete.
Detailed Explanation
Emitter Coupled Logic (ECL) is a type of digital logic that is known for its high speed. The ECL logic families began with the introduction of the MECL-I series in 1962, which marked the entry of ECL into the digital logic world. In 1966, ON Semiconductor introduced the improved MECL-II series. However, over time, both of these families became outdated as newer technologies emerged.
Examples & Analogies
Think of ECL like the first smartphones that changed how we communicate. Just as those early phones were revolutionary at their time but became obsolete with the advent of smartphones, ECL technology was groundbreaking in its speed back then but has now been surpassed by newer technologies.

Currently, popular subfamilies of ECL logic include MECL-III (also called the MC1600 series), the MECL-10K series, the MECL-10H series, and the MECL-10E series (ECLinPS and ECLinPSLite). The MECL-10K series further divided into the 10100-series and 10200-series devices.
Detailed Explanation
Today, several ECL subfamilies are still in use, including MECL-III, which is often referred to as the MC1600 series, and several variants of MECL-10K. The MECL-10K series is specifically noted for its high performance and is categorized into series 10100 and 10200, allowing engineers to choose specific features and capabilities for their devices.
Examples & Analogies
Imagine a company producing various models of a popular car. Each model might have different features like sunroofs or hybrid options. Similarly, the various ECL subfamilies offer different features tailored for high-speed electronics, allowing designers to select the right 'model' for their project needs.
