TLV1704AMPWPSEP

Comparators Overview

The TLV1704AMPWPSEP is a quad comparator from Texas Instruments designed for space applications. It operates on a supply voltage range of 2.2V to 24V and features rail-to-rail inputs. The device offers low quiescent current of 55µA per channel, propagation delay of 560ns, and input offset voltage of 300µV. It includes radiation tolerance with SEL immunity up to 43MeV-cm2/mg and ELDRS free performance to 30krad(Si). The package is TSSOP-14.

Comparators Feature Summary

• Radiation-tolerant design suitable for space environments
• Rail-to-rail input common-mode voltage range
• Open-collector outputs allowing level shifting up to 24V above negative supply
• Space enhanced plastic construction with gold wire and NiPdAu lead finish

Comparators Applications

• Command & data handling (C&DH)
• Aircraft cockpit display
• Flight control unit
• Satellite electrical power system (EPS)

Comparators Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as tube or tape and reel. Confirm that the radiation qualification meets mission requirements. Ensure the operating temperature range aligns with environmental constraints. Check for any recent documentation updates regarding specifications.

Comparators Selection Notes

Select this component when radiation hardness is critical for space missions. Consider its wide supply voltage range and low power consumption for portable or satellite systems. Evaluate the open-collector output flexibility for wired-OR configurations. Verify compatibility with existing PCB layouts and thermal management strategies.

Comparators Part Context

This part belongs to the TLV1704-SEP family, which provides radiation-tolerant comparators in space-enhanced packages. It is distinct from standard commercial versions by its hardened design against single-event effects and total ionizing dose. The device is intended for high-reliability aerospace and defense applications where standard components may fail due to radiation exposure.

Comparators Replacement Considerations

Check for direct replacements within the TLV1704-SEP family, such as different packaging options like TLV1704AMPWTPSEP. Verify if automotive-grade alternatives like TLV1704-Q1 meet radiation requirements. Ensure pinout and electrical characteristics match before substitution.
