JM54AC373BSA-RH

Latches Overview

The JM54AC373BSA-RH is an octal D-type transparent latch with 3-state outputs manufactured by National Semiconductor. It belongs to the AC series of high-speed CMOS logic functions. The device features a single functional block handling eight bits of data with true output polarity. It utilizes a ceramic dual-in-line package (CDIP) designed for side-brazed mounting, suitable for demanding environments. The component operates on a 5 V power supply and supports a wide temperature range from -55 °C to +125 °C. Propagation delay is specified at 16 ns under nominal conditions.

Latches Feature Summary

• Octal D-type transparent latching architecture with three-state bus interface outputs
• High-speed CMOS technology optimized for AC series performance metrics
• Hermetic ceramic metal-sealed cofired packaging for radiation hardness and environmental stability

Latches Applications

• Aerospace bus interface systems requiring radiation tolerance
• Military-grade data storage and buffering applications
• High-reliability industrial control systems operating in extreme temperatures

Latches Procurement Notes

Verify the specific suffix 'RH' against the manufacturer's current documentation to confirm radiation hardening specifications and hermetic sealing requirements. Ensure the ordering information matches the exact CDIP20 side-brazed package variant. Confirm RoHS compliance status as indicated in related datasheets, noting potential non-compliance for certain military variants. Validate that the supplier provides traceability to original manufacturing standards.

Latches Selection Notes

Select this component when system design requires radiation-hardened octal latches with high-speed CMOS characteristics. The hermetic ceramic package is essential for aerospace or defense applications exposed to ionizing radiation or harsh thermal cycles. Compare propagation delays and output drive capabilities against other AC series devices to ensure compatibility with system timing constraints and load requirements.
