JM38510/65503BRA

Overview

The JM38510/65503BRA is a military-grade octal bus transceiver manufactured by Texas Instruments. It features 3-state outputs and operates within a wide voltage range of 2 V to 6 V. The device supports high-current drive capabilities, enabling direct connection to bus lines or up to 15 LSTTL loads. It utilizes CMOS technology for low power consumption, with a maximum static current of 80 µA. The component is housed in a 20-lead Ceramic Dual In-Line Package (CDIP) and is rated for an operating temperature range of -55 °C to 125 °C.

Feature Summary

• Octal bidirectional data bus transceiver architecture
• High-current 3-state outputs for direct bus driving
• Wide operating voltage range from 2 V to 6 V
• Low power consumption with 80 µA maximum static current

Applications

• Asynchronous two-way communication between data buses
• Military and aerospace electronic systems requiring radiation tolerance
• High-performance computing bus interfaces
• Industrial control systems with strict environmental ratings

Procurement Notes

Verify the specific suffix BRA indicates the ceramic dual in-line package configuration. Confirm military screening levels and lot traceability requirements prior to ordering. Ensure compatibility with existing board layouts for 20-lead CDIP footprints. Check for lead-free compliance status if required by specific program regulations. Validate that the 2V to 6V supply range matches the system design constraints.

Selection Notes

Select this component when an octal transceiver with high-drive capability and wide voltage tolerance is required. It is suitable for applications needing direct interfacing with LSTTL loads without additional buffering. Consider the CDIP package for through-hole mounting in ruggedized environments. Evaluate the 80 µA static current against total system power budgets. Ensure the -55 °C to 125 °C temperature range meets operational extremes.

Part Context

This part belongs to the SN54HC245 family of octal bus transceivers. It shares functional similarities with commercial SN74HC245 devices but offers extended temperature ranges and military qualification. The JM38510 prefix denotes a MIL-PRF-38534 qualified hybrid microcircuit. It serves as a robust interface solution for critical data transmission paths in defense and space applications.

Replacement Considerations

SN54HC245BWR is a pin-compatible alternative within the same family. Verify package differences between CDIP and SOIC formats during substitution. Ensure voltage and current specifications remain compatible with the target application.
