SN54SC8T573MPWTSEP

Latches Overview

The SN54SC8T573MPWTSEP is a radiation-tolerant octal transparent D-type latch with 3-state outputs. It operates on a single supply voltage ranging from 1.2V to 5.5V and supports data rates up to 150Mbps at 5V or 3.3V VCC. The device features integrated voltage level translation, enabling up-translation from 1.2V to 5.0V and down-translation from 5.5V to 1.8V. It provides TID performance assurance up to 30krad(Si) and is immune to SEL up to 50MeV-cm2/mg. The component utilizes a 20-pin TSSOP package.

Latches Feature Summary

• Radiation tolerance with total ionizing dose assurance up to 30krad(Si) and single-event latch-up immunity up to 50MeV-cm2/mg
• Integrated voltage level translation supporting both up-translation and down-translation across multiple logic families
• Space-enhanced plastic construction featuring Au bondwires and NiPdAu lead finishes for aerospace reliability
• Balanced CMOS 3-state outputs designed for driving highly capacitive or low-impedance loads

Latches Applications

• Translation between communication modules and system controllers
• Implementing buffer registers and bidirectional bus drivers
• Controlling indicator LEDs in digital signal paths

Latches Procurement Notes

Verify the specific VID (Vendor Item Drawing) number required for your procurement contract. Confirm that the ordering suffix matches the exact package and tape/reel specifications needed for your assembly line. Ensure the radiation lot acceptance testing requirements align with your mission's radiation environment constraints before finalizing the order.

Latches Selection Notes

Select this component when designing systems requiring radiation hardness for space or high-altitude applications. It is suitable for interfacing different voltage domains within a single-supply architecture. Consider the thermal resistance metrics if operating near the maximum temperature limits. Verify input transition rates to prevent excessive power consumption during operation.
