JM54AC244BSA-RH

Overview

The JM54AC244BSA-RH is an octal buffer and line driver manufactured by National Semiconductor. It features non-inverting outputs with three-state capability, allowing multiple drivers to share a bus. The device operates within a voltage range of 2V to 6V and supports data rates up to 100 MHz. It is housed in a 20-lead Ceramic Flat Pack (CFP) package designed for high reliability in military and aerospace applications.

Feature Summary

• Octal configuration providing eight independent buffering channels
• Three-state output control for efficient bus sharing
• High-speed operation suitable for demanding digital systems
• Military-grade construction ensuring reliability in extreme environments

Applications

• Military communication systems requiring high reliability
• Aerospace data bus architectures
• Industrial control systems operating in harsh conditions
• Test and measurement equipment interfaces

Procurement Notes

Verify the specific suffix 'BSA' corresponds to the ceramic flat pack package variant. Confirm that the component meets all required environmental specifications for your application. Ensure compatibility with existing board layouts due to the specific pinout of the 20-CFP package. Check for any lead-free or RoHS exemptions if applicable to your regulatory requirements.

Selection Notes

Select this component when an octal buffer with three-state outputs is required for high-reliability applications. Consider the 20-CFP package size for mechanical constraints. Evaluate the 2V to 6V operating range against your system power supply. Compare performance metrics such as propagation delay and current drive against alternative logic families if speed or load requirements differ.

Part Context

This part belongs to the 54AC series of logic devices, which are known for their high speed and low power consumption compared to earlier standards. The 'JM' prefix typically indicates a military-grade qualification level. The AC family offers improved performance over standard TTL while maintaining CMOS input characteristics, making it suitable for mixed-logic systems.

Replacement Considerations

Direct substitutes include other 54AC244 variants from National Semiconductor or Texas Instruments. Verify package compatibility, as the CFP form factor is distinct. Ensure that any replacement maintains the same three-state functionality and voltage operating range. Cross-reference pinouts to confirm electrical equivalence without modification.
