Overview
The JM54ACT244SSA-R is an octal buffer and line driver manufactured by National Semiconductor. It features two elements with four bits per element, providing non-inverting logic functions. The device operates within a supply voltage range of 4.5V to 5.5V. It utilizes a 20-lead CFP package. The component includes three-state outputs designed for bus-oriented transmission and reception applications.
Feature Summary
- Provides non-inverting buffering for digital signals
- Supports three-state output control for bus sharing
- Designed for memory address and clock driving
Applications
- Memory address drivers
- Clock drivers
- Bus-oriented transmitter/receiver circuits
Procurement Notes
Verify the manufacturer designation as National Semiconductor or its successor entities due to corporate acquisitions. Confirm the specific suffix 'R' indicates reel packaging if required for automated assembly. Ensure the 20-CFP package type matches the target PCB footprint. Cross-reference the full part number against current distributor catalogs to confirm availability status and authenticity of the source component.
Selection Notes
Select this component when an octal non-inverting buffer with three-state capability is required. It is suitable for systems operating at standard 5V logic levels. Consider the 20-CFP package constraints for board layout. Verify that the input and output voltage specifications align with the system's power supply rails before integration into the design.
Part Context
This part belongs to the 54ACT series of high-speed CMOS logic devices. The 54ACT series is characterized by performance comparable to the older 54LS series but with lower power consumption. The '244' designation specifically identifies the octal buffer configuration with three-state outputs within this logical family hierarchy.
Replacement Considerations
Compatible substitutes include the JM54ACT244S2A-R in a 20-LCCC package from the same manufacturer. Other generic equivalents may exist within the 54ACT244 family, provided pin compatibility and electrical characteristics are verified.
