SY100H601JC

Translators, Level Shifters Overview

The SY100H601JC is a 9-bit ECL-to-TTL translator manufactured by Micrel, now part of Microchip Technology. It operates with dual supplies: VCCT at +5.0V and VEE between -4.2V and -5.5V. The device provides flow-through translation from MECL 100K compatible inputs to TTL outputs. It features 3-state control via separate OEECL and OETTL pins. Propagation delay is specified as 4.8ns maximum into 50pF and 9.6ns into 200pF load capacitance.

Translators, Level Shifters Feature Summary

• Provides 9-bit parallel translation from ECL logic levels to TTL logic levels
• Features independent 3-state enable controls for both ECL and TTL domains
• Includes dedicated power and ground pins to minimize switching noise
• Compatible with MECL 100K input signal standards

Translators, Level Shifters Applications

• Byte-parity generation circuits
• Interface between high-speed ECL processors and TTL peripheral systems
• Data bus conversion in mixed-logic environments

Translators, Level Shifters Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Micrel before acquisition by Microchip. Confirm the specific ordering suffix matches the required package type and lead finish. Check current lifecycle status, as older Micrel parts may be discontinued or not recommended for new designs. Ensure supply chain documentation accurately reflects the transition from Micrel to Microchip branding.

Translators, Level Shifters Selection Notes

Select this component when interfacing MECL 100K logic families with standard TTL loads requiring byte-wide translation. Consider the 28-pin PLCC package constraints for PCB layout. Evaluate the dual-supply requirement (-5V and +5V) against available system rails. Verify that the 3-state control requirements align with the separate OEECL and OETTL pin configuration provided by this device.

Translators, Level Shifters Part Context

This device belongs to the SY10/100H601 series of 9-bit translators. It is functionally equivalent to the MC10H/100H601. The 'SY100' prefix indicates compatibility with 100K ECL levels, distinguishing it from the SY10H variant which supports 10KH levels. Both variants share identical pinouts and electrical characteristics regarding the TTL output stage.

Translators, Level Shifters FAQ

What is the difference between the SY10H601 and SY100H601?

The primary difference is ECL input compatibility. The SY10H601 supports MECL 10KH levels, while the SY100H601 supports 100K levels.

How are the 3-state outputs controlled?

The device provides two separate 3-state control inputs: OEECL for ECL-level triggering and OETTL for TTL-level triggering.
