JM38510/38301B2A

Overview

The JM38510/38301B2A is an octal buffer and line driver manufactured by Texas Instruments. It features eight independent channels with three-state outputs, designed for high-speed digital applications. The device operates within a supply voltage range of 4.5V to 5.5V and supports a load capacitance of up to 50 pF. It provides a low-level output current of 24 mA and a high-level output current of -400 μA. The component is housed in a 20-pin ceramic leadless chip carrier (CLCC) package and is rated for operation between -55°C and 125°C.

Feature Summary

• Octal configuration providing eight independent buffering channels
• Three-state output capability for bus-oriented systems
• High drive strength suitable for loading multiple loads
• Ceramic package construction for environmental stability

Applications

• Clock drivers and buffer circuits
• Bus-oriented architectures requiring signal isolation
• Memory address and data register drivers
• Control signal distribution in military or aerospace systems

Procurement Notes

Verify the specific suffix B2A corresponds to the ceramic CLCC package variant. Confirm that the procurement source provides traceability documentation required for MIL-STD components. Ensure the received units match the specified operating temperature range and package dimensions. Request test reports verifying electrical parameters against the official datasheet specifications before integration into critical designs.

Selection Notes

Select this component when an octal buffer with three-state control is required for high-reliability environments. The ceramic package offers superior thermal and mechanical stability compared to plastic alternatives. Consider the 24 mA sink current capability for driving heavy capacitive loads. Ensure system design accommodates the 20-pin CLCC footprint and associated soldering requirements for leadless packages.

Part Context

This part belongs to the JM38510 series, which encompasses military-grade logic devices produced under JESD-38 standards. The JM38510/38301B2A specifically implements the functional equivalent of commercial octal buffers but with enhanced reliability specifications. It is part of Texas Instruments' portfolio of radiation-hardened and high-reliability semiconductor solutions intended for defense and space applications.

Replacement Considerations

Direct replacements include other JM38510/38301 variants with compatible suffixes indicating identical functionality and pinout. Verify package compatibility when substituting with commercial equivalents such as the SN75464, ensuring voltage and current ratings are sufficient.
