SN100KT5542DW

Translators, Level Shifters Overview

The SN100KT5542DW is an octal TTL-to-ECL translator manufactured by Texas Instruments. It features eight independent translation channels with inverted outputs, designed to interface between Transistor-Transistor Logic (TTL) and Emitter-Coupled Logic (ECL) families. The device operates within a supply voltage range of 3V to 5.5V and utilizes a 24-pin Small Outline Integrated Circuit (SOIC) package. It supports data rates up to 1.6ns propagation delay, ensuring efficient signal conversion for mixed-logic systems requiring robust level shifting capabilities.

Translators, Level Shifters Procurement Notes

Verify the RoHS compliance status carefully, as sources indicate this specific part may be non-compliant or obsolete compared to newer revisions. Confirm the exact package type and date code upon order confirmation. Ensure that the supplier provides traceability documentation. Check for availability constraints as stock levels fluctuate. Validate that the inverted output configuration matches your circuit design requirements before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when designing systems that require direct interfacing between TTL and ECL logic families without external discrete components. Consider the 24-pin SOIC package for surface-mount assembly compatibility. Evaluate the 1.6ns propagation delay against system timing budgets. Verify that the supply voltage range aligns with the target application's power rails. Ensure the inverted output characteristic does not conflict with downstream logic requirements.
