JM38510/65704BRA

Overview

The JM38510/65704BRA is a military-grade octal buffer and line driver manufactured by National Semiconductor. It features two non-inverting drivers, each handling four bits of data with tri-state outputs. The device operates within a supply voltage range of 2V to 6V and is housed in a 20-lead ceramic dual in-line package (CDIP). Designed for high-reliability applications, it supports bus-oriented systems requiring robust signal buffering and isolation.

Feature Summary

• Provides eight non-inverting buffer channels with independent tri-state control
• Operates on low voltage supplies ranging from 2V to 6V
• Constructed in hermetic ceramic dual in-line packaging for environmental resilience

Applications

• Military aerospace bus driver circuits
• High-reliability computer memory interface buffering
• Industrial control system signal isolation

Procurement Notes

Verify the specific suffix BRA indicates the correct package and temperature grade. Confirm RoHS status as non-compliant due to military specifications. Ensure the supplier provides traceability documentation required for defense contracts. Check moisture sensitivity level ratings before assembly to prevent package damage during soldering processes.

Selection Notes

Select this component when high noise immunity and low power consumption are critical for bus architectures. Compare against standard commercial HC series parts if military qualification is not required. Consider the CDIP package constraints for PCB layout and thermal management requirements in enclosed environments.

Part Context

This part belongs to the JM38510 family, which defines military-standard CMOS logic devices. National Semiconductor, now part of Texas Instruments, produced these components to meet strict MIL-PRF-38534 reliability standards. The 65704 designation specifically identifies the octal buffer configuration within this standardized logic family.

Replacement Considerations

Direct substitutes include other manufacturers' equivalents under the same MIL-PRF-38534 specification. Verify pin compatibility and electrical characteristics match the original design requirements before substitution.
