SY100ELT22ZC

Translators, Level Shifters Overview

The SY100ELT22 is a dual TTL-to-differential PECL translator manufactured by Microchip Technology. It operates on a single +5V supply and features PNP TTL inputs for minimal loading. The device provides differential PECL outputs compatible with positive ECL 100K logic levels. Key electrical parameters include a typical propagation delay of 300 ps, output-to-output skew under 100 ps, and a power supply current of 30 mA. It functions within a voltage range of 4.2V to 5.5V and an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Dual-channel architecture translating TTL signals to differential PECL outputs
• PNP-based TTL input structure designed for minimal signal loading
• Low-skew design ensuring precise timing alignment between channels
• Flow-through pinout configuration simplifies PCB layout

Translators, Level Shifters Applications

• Clock signal translation in high-speed digital systems
• Data signal level shifting between TTL and PECL domains
• Interface bridging in telecommunications equipment
• Test and measurement instrumentation requiring low jitter translation

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix (e.g., ZG for tube, TR for reel) as it determines packaging quantity and media type but does not alter the core device function. Confirm that the industrial temperature grade (-40°C to +85°C) meets your environmental requirements. Ensure compatibility with standard 8-Lead SOIC footprint during procurement planning.

Translators, Level Shifters Selection Notes

Select this component when a dual-channel solution is required to convert TTL inputs to differential PECL outputs with minimal propagation delay. It is suitable for designs needing low-power operation at 30 mA and compatibility with positive ECL 100K levels. Consider the 8-lead SOIC package constraints and verify that the 5V supply rail aligns with your system's power distribution network.

Translators, Level Shifters Part Context

The SY100ELT22 belongs to the Precision Edge family of translators from Microchip Technology. This series focuses on high-speed signal integrity and low skew performance. The device replaces older variants like the SY10ELT22, which has been discontinued. It serves as a specialized interface bridge within the broader logic IC category, specifically targeting voltage level translation applications.

Translators, Level Shifters Replacement Considerations

The SY10ELT22 is a discontinued predecessor model. Verify if the SY100ELT22ZG or SY100ELT22ZG-TR directly substitutes existing SY10ELT22 designs without schematic changes due to identical pinouts and functionality.

Translators, Level Shifters FAQ

What is the maximum operating voltage for the SY100ELT22?

The absolute maximum power supply voltage rating is +7.0V, but the recommended operating range is 4.2V to 5.5V.

Does the SY100ELT22 support AC-coupled inputs?

Yes, the device supports differential, single-ended, or AC-coupled interfaces to the TTL inputs.

What happens if the TTL inputs are left open?

Under open input conditions, the internal biasing forces the output low to provide added stability.
