Overview
The 54LS353DM/B is a dual 1-of-4 data selector/multiplexer manufactured by Rochester Electronics. It contains two independent multiplexers, each capable of selecting one of four data inputs based on binary address lines. The device features three-state outputs, allowing multiple devices to share bus systems without interference. It utilizes TTL logic technology and operates within standard military temperature ranges.
Feature Summary
- Dual independent 1-of-4 multiplexer architecture
- Three-state outputs for bus-compatible interfacing
- Separate strobe inputs for individual section control
Applications
- Bus-oriented system data routing
- Digital signal selection in military avionics
- Data acquisition system input switching
Procurement Notes
Verify the specific suffix DM/B against the manufacturer's official documentation to confirm package type and material composition. Ensure the component meets the required MIL-PRF-38535 qualification class if applicable to your system. Confirm lead-free status and RoHS compliance through the provided datasheet before integration.
Selection Notes
Select this component when dual independent multiplexing with high-impedance outputs is required for bus architectures. Verify that the logic family characteristics match the system voltage and speed requirements. Check the pinout compatibility with existing PCB layouts to ensure seamless replacement or design inclusion.
Part Context
This part belongs to the SN54/74LS series of logic integrated circuits. It is produced by Rochester Electronics, which often sources components from original manufacturers or recreates them using approved intellectual property.
