SY100S324JY

Translators, Level Shifters Overview

The SY100S324JY 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 a 28-pin PLCC package. The device features differential outputs and an internal enable function that holds outputs in defined states when activated. Electrical specifications include a maximum propagation delay of 1.4ns, an IEE minimum of -70mA, and an extended supply voltage range for VEE from -4.2V to -5.5V.

Translators, Level Shifters Feature Summary

• Provides differential outputs capable of functioning as either an inverting/non-inverting translator or differential line drivers.
• Includes an internal common Enable input that forces all inverting outputs HIGH and non-inverting outputs LOW when held LOW.
• Offers voltage and temperature compensation designed to improve noise immunity against ground system voltage gradients.

Translators, Level Shifters Applications

• Converting TTL logic signals to 100K ECL levels
• Differential line driving applications
• Systems requiring high common-mode rejection between TTL and ECL grounds

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix to confirm package type and lead finish. The 'JY' suffix indicates an industrial operating temperature range and a matte-tin Pb-free bar-line indicator. Confirm availability status as this component may be discontinued or restricted for new designs. Ensure compatibility with existing PCB footprints for the 28-pin PLCC form factor before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing TTL sources with ECL destinations requiring differential signaling. It is suitable for environments needing robust noise immunity through voltage and temperature compensation. Consider the 1.4ns propagation delay for timing constraints. Verify that the power supply requirements align with the specified VEE and VTTL ranges for proper operation.

Translators, Level Shifters Part Context

This part belongs to the SY100S324 series of hex translators. It is functionally and pinout compatible with Fairchild F100K devices. The manufacturer notes it is twice as fast as the Fairchild 324 equivalent. It is categorized under Logic ICs within the broader family of translation and interface components.

Translators, Level Shifters Replacement Considerations

The datasheet confirms functional and pinout compatibility with the Fairchild F100K. Designers should verify electrical parameter margins against the original design specifications when substituting parts.
