100324SC

Overview

The onsemi 100324SC is a low-power hex TTL-to-ECL translator housed in a 24-lead Small Outline Integrated Circuit (SOIC) package. It converts standard or Schottky TTL logic levels to 100K ECL logic levels, featuring differential outputs for use as line drivers or inverters. The device operates within a VEE range of -4.2V to -5.7V and includes voltage compensation. It provides 2000V ESD protection and features an active-low common Enable input that forces all true outputs LOW and inverting outputs HIGH when asserted.

Feature Summary

• Differential outputs allow flexible configuration as inverting/non-inverting translators or differential line drivers.
• Voltage compensated output levels ensure stability across the full operating supply range.
• High common mode rejection capability mitigates voltage gradients between separate TTL and ECL ground systems.
• Integrated ESD clamps provide robustness against electrostatic discharge events.

Applications

• Converting TTL logic signals to ECL logic levels in mixed-signal systems.
• Acting as a differential line driver for high-speed data transmission.
• Interfacing between disparate logic families requiring level translation.

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific ordering suffix matches the required package type and temperature grade. Review the manufacturer's datasheet for absolute maximum ratings and recommended operating conditions prior to integration. Ensure compliance with relevant environmental directives such as RoHS if applicable to the target market.

Selection Notes

Select this component when interfacing TTL sources with ECL destinations requiring low power dissipation. Consider the 24-SOIC package for surface-mount assembly constraints. Evaluate the propagation delay specifications against system timing requirements. Verify that the available supply voltages align with the specified VEE and VTTL ranges for proper operation.

Part Context

This device belongs to the 100324 series of low-power hex translators. It is pin and function compatible with the 100124 model but offers approximately half the power dissipation. The series is designed to ease system cooling requirements while maintaining similar AC performance characteristics to its predecessors.

Replacement Considerations

The 100124 is documented as a pin and function compatible alternative within the same family. Verify compatibility by comparing electrical specifications and package dimensions before substitution.
