SY10H350JZ-TR

Translators, Level Shifters Overview

The SY10H350JZ-TR is a PECL-to-TTL translator manufactured by Microchip Technology, formerly Micrel. It consists of four translators with differential inputs and TTL outputs in a 20-pin PLCC package. The device operates on a single 5V power supply with separate VCCE (PECL) and VCCT (TTL) pins that are not internally connected to isolate noisy logic runs. It features 3-state outputs disabled by a HIGH level on the common OE input. Typical propagation delay is 3.5ns, with an operating temperature range of 0°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides four independent translators converting differential PECL signals to standard TTL levels
• Features three-state outputs controlled by a common Output Enable pin for bus isolation
• Utilizes separate internal power domains to electrically isolate noisy TTL circuits from quiet ECL circuits

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 component authenticity through authorized channels as this part may be obsolete. Confirm lead finish specifications, specifically Matte-Sn for Pb-Free variants, against current design requirements. Ensure the tape and reel packaging matches automated assembly needs. Validate that the commercial temperature range meets environmental constraints.

Translators, Level Shifters Selection Notes

Select this component when interfacing high-speed PECL sources with TTL destinations within a mixed-voltage system. The separate power pins facilitate effective noise isolation on the PCB layout. Verify compatibility with existing MC10H350 designs if cross-manufacturer substitution is required.

Translators, Level Shifters Part Context

This device belongs to the 10H series of high-speed logic translators. Originally produced by Micrel, Inc., it was acquired by Microchip Technology. The JZ suffix indicates a Pb-Free plastic leaded chip carrier package with a matte tin bar-line indicator, while the TR suffix denotes tape and reel packaging.

Translators, Level Shifters Replacement Considerations

The datasheet states the device is fully compatible with the MC10H350.
