JM38510/34105BRA

Overview

The JM38510/34105BRA is a military-grade octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It belongs to the SN54F374 series within the F logic family, featuring TTL input compatibility and three-state outputs. The device is housed in a 20-lead ceramic dual in-line package (CDIP) designed for through-hole mounting. It operates reliably across an extended temperature range of -55°C to +125°C with a supply voltage between 4.5V and 5.5V. Key electrical characteristics include a propagation delay of 10 ns, a high-level output current of -3 mA, and a low-level output current of 24 mA.

Feature Summary

• Octal configuration providing eight independent edge-triggered D-type flip-flops in a single integrated circuit
• Three-state outputs enabling direct bus-driven connections without external pull-up or pull-down resistors
• TTL-compatible inputs ensuring seamless integration with standard digital logic families
• Military-grade construction utilizing ceramic packaging for enhanced durability in extreme environments

Applications

• High-reliability aerospace computing systems requiring radiation-hardened or robust digital storage
• Military communication equipment operating under severe thermal and mechanical stress conditions
• Industrial control systems demanding long-term stability and wide temperature tolerance
• Defense electronics architectures utilizing standard TTL logic interfaces for data latching

Procurement Notes

Verify that the specific part number suffix matches the required case outline and lead finish specifications defined in MIL-M-38510/341F. Confirm compliance with MIL-PRF-38535 Class standards during acquisition. Ensure the supplier provides full traceability documentation. Check for availability constraints as this component may be subject to limited production runs or special order requirements from the manufacturer.

Selection Notes

Select this component when designing systems that require octal data storage with bus-oriented output control. It is suitable for applications necessitating TTL input levels and high-speed operation with a 10 ns propagation delay. Consider this part for environments where standard plastic packages are insufficient due to extreme temperature variations or physical stress. Ensure the design accommodates the specific power dissipation and current drive capabilities of the F logic family.

Part Context

This microcircuit falls under the SN54F374 series, representing Advanced Schottky TTL technology. It is governed by the MIL-M-38510/341F specification for monolithic silicon bipolar flip-flops. The device serves as a critical storage element in complex digital logic designs, offering higher speed and lower power consumption compared to earlier standard TTL counterparts while maintaining backward compatibility with existing system architectures.

Replacement Considerations

Direct replacements must adhere to the same MIL-M-38510/341F specification. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength. Cross-reference with other manufacturers producing qualified SN54F374 equivalents. Ensure any substitute maintains the CDIP-20 package form factor and meets the required military qualification standards.
