SY100S324JY-TR

Translators, Level Shifters Overview

The SY100S324JY-TR is a low-power hex TTL-to-ECL translator manufactured by Microchip Technology. It converts TTL logic levels to industry-standard 100K ECL levels using differential outputs. The device operates with VEE from –4.2V to –5.5V and VTTL from +4.5V to +5.5V. Maximum propagation delay is 1.4ns, with typical values of 850ps. Input HIGH voltage is guaranteed up to 5.0V, while LOW is 0.8V. It features an active-low Enable input and internal 75kΩ pull-down resistors. The component is housed in a 28-pin PLCC package.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix (JY vs JCTR) to confirm the industrial temperature range and tape-and-reel packaging configuration. Confirm RoHS compliance status as the datasheet indicates Pb-Free options are available for new designs. Check current availability as the component may be subject to lifecycle changes or discontinuation notices.

Translators, Level Shifters Selection Notes

Select this component when interfacing TTL sources with ECL destinations requiring differential signaling. Ensure the design accommodates the specified VEE and VTTL supply ranges. Consider the 28-pin PLCC package constraints for PCB layout. Verify that the maximum propagation delay meets system timing requirements.
