JM38510/32502BSA

Latches Overview

The JM38510/32502BSA is an octal D-type transparent latch manufactured by Texas Instruments. It features eight independent D-type latches with tri-state outputs, designed for high-speed data storage and bus interfacing applications. The device operates within a military-grade temperature range of -55°C to 125°C and utilizes a 20-lead ceramic flat pack (CFP) package. As part of the 54LS series, it provides reliable performance in demanding environments requiring robust signal integrity and controlled output states.

Latches Feature Summary

• Octal configuration providing eight independent D-type transparent latches for parallel data handling
• Tri-state outputs enabling direct connection to system buses without external buffers
• Military-grade reliability certified for operation across extended temperature ranges from -55°C to 125°C
• Ceramic flat pack construction ensuring durability in harsh environmental conditions

Latches Applications

• High-reliability military aerospace data acquisition systems
• Industrial control interfaces requiring extended temperature tolerance
• Bus-oriented memory storage architectures
• Signal buffering in radiation-hardened electronic circuits

Latches Procurement Notes

Verify the specific suffix BSA confirms the ceramic flat pack package and commercial/military grade qualification. Ensure the component meets MIL-PRF-38534 standards if required for your application. Confirm lead times and availability directly with authorized distributors as this is a specialized military-grade component. Check for RoHS compliance status if applicable to your procurement requirements.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for bus-driven applications. Consider the 54LS series speed and power characteristics against system requirements. Evaluate the 20-lead CFP package compatibility with existing PCB layouts and thermal management strategies. Verify that the operating temperature range aligns with the environmental conditions of the final assembly.

Latches Part Context

This component belongs to the Texas Instruments 54LS logic family, known for low-power Schottky technology. The JM38510 prefix indicates a military-grade specification under MIL-PRF-38534. It serves as a critical interface element in digital systems where data retention and bus isolation are essential. The device complements other LS-series components like transceivers and buffers in complex logic designs.

Latches Replacement Considerations

Direct replacements include other 54LS373 variants from qualified manufacturers meeting MIL-PRF-38534 specifications. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength. Ensure the substitute component offers equivalent tri-state functionality and temperature range certification.
