54SC8T9541MPWTSEP

Overview

The SN54SC8T9541MPWTSEP is a radiation-tolerant, octal buffer and driver featuring 3-state outputs and Schmitt-trigger inputs. It supports a wide operating voltage range of 1.2V to 5.5V and provides single-supply voltage translation capabilities for both up-conversion (e.g., 1.2V to 5.0V) and down-conversion (e.g., 5.0V to 1.8V). The device ensures Total Ionizing Dose performance assurance up to 30krad(Si) with characterization up to 50krad(Si), and offers Single-Event Latch-Up immunity up to 50MeV-cm2/mg at 125°C. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Radiation tolerance with TID assurance up to 30krad(Si) and SEL immunity up to 50MeV-cm2/mg
• Integrated voltage level translation supporting up and down conversion between standard CMOS levels
• Schmitt-trigger inputs providing hysteresis for noise immunity on slow or noisy signals
• Space-enhanced plastic construction with Au bondwires and NiPdAu lead finishes

Applications

• Translation between communication modules and system controllers
• Enabling or disabling digital signals in aerospace systems
• Controlling indicator LEDs in harsh environments

Procurement Notes

Verify the specific VID V62/25633-01XE against procurement requirements. Confirm that the radiation lot acceptance testing meets project specifications. Ensure the space-enhanced packaging aligns with NASA ASTM E595 outgassing standards. Validate that the extended product life cycle supports long-term mission needs.

Selection Notes

Select this component when radiation hardness is required for octal buffering applications. It is suitable for designs needing flexible voltage translation across a broad supply range. Consider its thermal characteristics and package size for PCB layout constraints. Verify input signal transition rates to prevent excessive power consumption.
