M38510/34803BRA

Overview

M38510/34803BRA is a military-grade octal bus transceiver manufactured by Texas Instruments under the SN54F245 designation. It features bidirectional data transmission between two 8-bit buses controlled by a DIR input and an OE input for isolation. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a full military temperature range from -55 °C to 125 °C. It utilizes a 20-pin Ceramic Dual In-Line Package (CDIP).

Feature Summary

• Bidirectional data transfer capability between A and B buses.
• Three-state outputs for direct bus line driving.
• Output enable control for effective bus isolation.

Applications

• Asynchronous communication between data buses.
• Military and defense electronic systems.
• High-reliability industrial control applications.

Procurement Notes

Verify that the component matches the specific M38510/34803BRA part number, as this indicates a QML certified military version. Confirm the package type is CDIP with 20 pins. Ensure the supplier provides traceability documentation required for military specifications.

Selection Notes

Select this component when a high-speed octal bus transceiver is required for harsh environments. It is suitable for designs needing bidirectional data flow with strict temperature stability. Compare against standard catalog versions if military certification is not mandatory.

Part Context

This part belongs to the SN54F245 family of octal bus transceivers. It shares functionality with commercial variants but meets stricter MIL-M-38510 standards. The BRA suffix identifies the specific ceramic dual in-line package configuration available for this series.
