SY10H350JZ

Translators, Level Shifters Overview

The SY10H350JZ is a PECL-to-TTL translator manufactured by Microchip Technology, originally produced by Micrel. It features four translators with differential inputs and TTL outputs in a 20-pin PLCC package. The device operates on a single 5V power supply, utilizing separate VCCE (PECL) and VCCT (TTL) pins that are not internally connected to isolate noisy logic runs. Key electrical parameters include a typical propagation delay of 3.5ns, an operating temperature range of 0°C to +85°C, and a maximum input voltage of VCC+0.5V.

Translators, Level Shifters Feature Summary

• Provides four independent translators converting differential PECL signals to TTL levels
• Features three-state outputs controlled by a common Output Enable input
• Utilizes separate internal power domains for PECL and TTL sections to minimize noise coupling

Translators, Level Shifters Applications

• Systems incorporating both ECL and TTL logic operating off a common power supply
• Inverting or non-inverting translation between logic families
• Differential line receiver applications

Translators, Level Shifters Procurement Notes

Verify the component status as the datasheet indicates it is not recommended for new designs. Confirm the specific ordering suffix 'JZ' corresponds to the Pb-Free package with Matte-Sn finish and bar-line indicator. Ensure compatibility with existing PCB footprints for the 20-pin PLCC J20-1 package before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing high-speed PECL sources with standard TTL loads within a mixed-voltage environment. The separate power pins allow for distinct ground planes or filtering strategies for the PECL and TTL sections. Verify that the required propagation delay and output drive capabilities meet the system timing requirements.

Translators, Level Shifters Part Context

This part belongs to the SY10H350 series of voltage level translators. It is functionally compatible with the MC10H350. The manufacturer acquired the original Micrel logic product lines, which explains the branding transition found in distribution channels.

Translators, Level Shifters Replacement Considerations

The datasheet notes full compatibility with the MC10H350. Designers should verify pinout and electrical specifications against the MC10H350 datasheet to ensure interchangeability.
