SY100S324JC

Translators, Level Shifters Overview

The SY100S324JC is a hex TTL-to-ECL translator manufactured by Microchip Technology in a 28-pin PLCC package. It operates with VEE from –4.2V to –5.5V and VTTL from +4.5V to +5.5V. The device features a maximum propagation delay of 1.4ns, an IEE minimum of –70mA, and internal 75kΩ input pull-down resistors. It provides differential outputs for use as line drivers or translators.

Translators, Level Shifters Feature Summary

• Converts TTL logic levels to industry standard 100K ECL levels
• Provides differential outputs suitable for inverting/non-inverting translation or line driving
• Includes voltage and temperature compensation for improved noise immunity
• Features high common mode rejection to overcome ground system voltage gradients

Translators, Level Shifters Applications

• TTL to ECL level translation
• Differential line driving
• High-speed digital signal interfacing

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix (e.g., JC vs JCTR) to confirm the package type and reel configuration. Confirm RoHS compliance status, noting that Pb-Free variants exist. Check current lifecycle status as this component may be restricted for new designs. Ensure supply chain sources provide valid datasheets matching the exact part number.

Translators, Level Shifters Selection Notes

Select this component when TTL inputs must interface with 100K ECL systems requiring differential signaling. Consider the 28-pin PLCC package constraint. Evaluate the need for voltage/temperature compensation and high common-mode rejection capabilities. Verify power supply requirements align with the specified VEE and VTTL ranges.

Translators, Level Shifters Part Context

This part belongs to the SY100S series of high-speed logic devices originally developed by Micrel, now under Microchip Technology. The series focuses on translating between different logic families like TTL and ECL. The SY100S324 specifically addresses hex translation needs within this ecosystem.
