JM38510/33203BRA

Overview

The JM38510/33203BRA is a military-grade octal buffer and driver manufactured by Texas Instruments. It features eight channels with three-state outputs, designed for high-speed digital applications. The device operates within a voltage range of 4.5 V to 5.5 V and exhibits a propagation delay of 5.2 ns at 5 V. It supports an output current of up to 24 mA per channel and has a load capacitance specification of 50 pF. The component is housed in a 20-pin ceramic dual in-line package (CDIP) and functions reliably across an extended temperature range from -55 °C to 125 °C.

Feature Summary

• Octal configuration providing eight independent buffering channels
• Three-state output capability for bus-oriented systems
• High drive strength supporting significant source and sink currents
• Military-grade construction ensuring reliability in extreme environments

Applications

• Bus-oriented memory systems requiring high-speed data transfer
• Clock distribution networks demanding low propagation delay
• Industrial control systems operating in harsh thermal conditions
• Military communication equipment requiring ruggedized logic components

Procurement Notes

Verify the specific suffix BRA against official Texas Instruments documentation to confirm pinout and electrical characteristics match your design requirements. Ensure that the CDIP package dimensions align with your PCB footprint constraints. Confirm that the supplier provides traceability documentation suitable for military or aerospace procurement standards, as this part falls under the MIL-STD-38510 specification.

Selection Notes

Select this component when designing systems that require multiple buffered outputs with tri-state control on a shared bus architecture. The choice is driven by the need for high current drive capabilities beyond standard CMOS limits and the requirement for operation in wide temperature ranges. Consider the 20-pin CDIP package if hermetic sealing is necessary for the application environment.

Part Context

This part belongs to the SN54 series of logic devices, which are characterized by their military-grade qualification and extended temperature ratings compared to commercial SN74 equivalents. The JM38510 designation indicates compliance with MIL-STD-38510 standards for integrated circuits. It serves as a robust solution for critical digital interfaces where signal integrity and environmental resilience are paramount.

Replacement Considerations

Direct replacements include other SN54F244 variants meeting MIL-STD-38510 specifications. Verify compatibility regarding package type and pin assignment before substitution. Cross-reference with other manufacturers offering equivalent military-grade octal buffers with three-state outputs.
