JM54ACT244BRA-R

Overview

The JM54ACT244BRA-R is an octal buffer and line driver manufactured by National Semiconductor. It features non-inverting logic with tri-state outputs, designed for high-speed digital applications. The device operates at a maximum voltage of 5.5V and is housed in a 20-pin CERDIP package. It functions as a memory address driver, clock driver, or bus-oriented transmitter/receiver, providing robust signal integrity for complex electronic systems.

Feature Summary

• Octal buffer configuration with tri-state output capability
• Non-inverting logic design for signal transmission
• Suitable for memory address and clock driving applications

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receivers

Procurement Notes

Verify the manufacturer designation as National Semiconductor, now part of Texas Instruments, to ensure authenticity. Confirm the specific suffix 'BRA-R' corresponds to the 20-CERDIP package variant. Check for updated datasheets from TI archives, as original National Semiconductor documentation may be archived. Ensure the component meets military-grade specifications if implied by the 'JM' prefix, requiring rigorous quality assurance checks upon receipt.

Selection Notes

Select this component when an octal buffer with tri-state control is required for bus isolation or signal buffering. The ACT series offers faster switching speeds compared to standard AC series devices. Consider the 20-CERDIP package for through-hole mounting requirements in legacy or high-reliability designs. Ensure supply chain compatibility with current inventory management systems given the component's age.

Part Context

This part belongs to the 54AC/54ACT family of octal buffers. These components are widely used in digital logic circuits for driving loads and isolating buses. The 'ACT' designation indicates advanced technology with higher speed performance. The 'JM' prefix typically denotes military-grade qualification, ensuring reliability under extreme conditions.

Replacement Considerations

Compatible substitutes include other 54ACT244 variants from Texas Instruments or equivalent manufacturers offering octal tri-state buffers. Verify pin compatibility and electrical characteristics such as propagation delay and output drive strength before substitution.
