Overview
The JM54AC244SRA-RH is an octal buffer and line driver manufactured by National Semiconductor. It features non-inverting logic with three-state outputs, designed for memory address driving, clock distribution, and bus-oriented transmission. The component operates within a supply voltage range of up to 6V and is housed in a 20-CDIP package.
Feature Summary
- Octal buffer configuration providing eight independent non-inverting channels
- Three-state output capability for effective bus management and isolation
- Designed for high-speed memory address and clock signal driving applications
Applications
- Memory address drivers
- Clock signal distribution
- Bus-oriented transmitter/receiver circuits
Procurement Notes
Verify the manufacturer designation as National Semiconductor or its successors, as corporate acquisitions may affect branding on legacy components. Confirm the specific suffix 'R' indicates tape-and-reel packaging if applicable, though datasheets often list CDIP. Ensure the part number matches the exact octal buffer specification to avoid confusion with similar AC series variants.
Selection Notes
Select this component when an octal, non-inverting buffer with three-state outputs is required for digital logic interfacing. It is suitable for applications needing high drive capability for buses or clocks. Consider the 20-CDIP package constraints for through-hole mounting requirements and verify voltage compatibility with the system's 6V maximum supply limit.
Part Context
This part belongs to the 54AC/74AC family of high-speed CMOS logic devices. The 'JM' prefix typically denotes military or extended temperature grade specifications from National Semiconductor. It serves as a standard interface solution for connecting microprocessors to memory or peripheral buses in industrial and commercial electronics.
Replacement Considerations
Compatible substitutes include the SN54AC244 or SN74AC244 series from Texas Instruments, which share identical pinouts and logical functions. Verify that replacement parts meet the same voltage and package requirements.
