Product Overview: MC100ELT28DTR2 - ON Semiconductor

The MC100ELT28DTR2 is a high-performance, dual differential PECL to TTL translator manufactured by ON Semiconductor. This integrated circuit is designed to address the needs of high-speed signal conversion from PECL (Positive Emitter Coupled Logic) levels to TTL (Transistor-Transistor Logic) levels, making it an essential component for systems that interface between these two logic families.

The device operates with a V_CC supply voltage range of 4.2V to 5.5V, which allows for compatibility with standard TTL power supply levels. The MC100ELT28DTR2 can translate signals up to a frequency of 2GHz, making it suitable for high-speed data communication and processing applications. Its differential PECL inputs incorporate a 75 kΩ pull-down resistor, ensuring that the inputs are not left floating when not actively driven.

The translator comes in a compact TSSOP-8 package, providing a space-efficient solution for densely packed PCBs. Its small footprint is especially beneficial in applications where board space is at a premium, such as telecommunications, computing, and networking equipment.

Key features of the MC100ELT28DTR2 include the following:

• Maximum input clock frequency of 2 GHz for high-speed operation.
• PECL to TTL signal level translation for seamless integration between logic families.
• On-chip bias resistors on the inputs, which minimize external component requirements.
• Compatible with MECL 10H ECL logic standards.
• Operating temperature range of -40°C to +85°C, suitable for industrial environments.
• Flow-through pinout for ease of PCB layout and signal routing.

The MC100ELT28DTR2 is an essential building block for designers looking to bridge the gap between PECL and TTL logic levels without compromising on speed or performance. Its robust design and high-speed capabilities make it an ideal choice for a wide range of applications in the modern digital world.
