SN10KHT5578DW

Translators, Level Shifters Overview

The SN10KHT5578DW is an octal TTL-to-ECL translator manufactured by Texas Instruments, designed for efficient signal translation between TTL and 10KH ECL environments. It integrates eight D-type edge-triggered flip-flops with noninverting outputs and an output enable control. The device operates within a temperature range of 0°C to 75°C, utilizing VCC (4.5V–5.5V) and VEE (-4.94V to -5.46V) supplies. Key electrical characteristics include a maximum clock frequency of 180 MHz, propagation delays ranging from 0.8 ns to 4 ns, and input/output voltage levels specific to the 10KH standard.

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized channels as counterfeit risks exist for legacy parts. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure supply chain stability given the component's age and potential discontinuation status. Validate package integrity against specified SOIC dimensions before soldering.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring direct interface between TTL inputs and 10KH ECL outputs. Consider the 24-pin SOIC package constraints and thermal impedance specifications. Evaluate power supply requirements for both VCC and VEE rails. Assess timing margins against the 180 MHz maximum clock frequency specification.

Translators, Level Shifters Part Context

This device belongs to the 10KHT series of high-speed logic translators produced by Texas Instruments. It serves as a bridge between different logic families, specifically addressing the voltage and speed differences between TTL and ECL standards. The DW suffix indicates a plastic small-outline package variant.

Translators, Level Shifters Replacement Considerations

Check for SN10KHT5578DWR or SN10KHT5578NT variants for tape-and-reel or DIP packaging options respectively. Verify pin compatibility and electrical specifications match before substitution.
