Overview
The 54F352LM/B is a dual 1-of-2 data selector/multiplexer manufactured by Rochester Electronics. It contains two independent multiplexers, each with two data inputs (D0, D1), one address select input (S), and one strobe input (G). The device features three-state outputs that allow direct interface with bus-oriented systems. When the strobe is low, the selected data input is transmitted to the output; when high, the output enters a high-impedance state. This component belongs to the SN54F35x family, designed for military-grade performance with extended temperature ranges.
Feature Summary
- Dual independent 1-of-2 multiplexer architecture
- Three-state outputs for bus system interfacing
- Separate strobe control for each section
Applications
- Military-grade data routing in avionics systems
- Bus-oriented logic interfaces requiring isolation
- High-reliability signal selection circuits
Procurement Notes
Verify the specific suffix 'B' against the manufacturer's official documentation to confirm package type and temperature range specifications. Ensure the component meets MIL-PRF-38535 Class Q or V requirements if applicable to the design. Confirm RoHS compliance status as military parts may vary. Request full datasheet and test reports from the supplier to validate electrical parameters against original OEM standards before integration.
Selection Notes
Select this component when dual independent multiplexing with three-state outputs is required in harsh environments. Compare propagation delay and power consumption against other F-series logic families. Verify that the operating voltage range matches the system supply. Consider the package compatibility and pinout alignment with existing PCB footprints during the design phase.
Part Context
This part is part of the SN54F35x series of dual multiplexers. Rochester Electronics produces these components using die/wafers from original suppliers or recreated IP with approval. They are tested to meet or exceed original data sheet specifications. The 54F series typically denotes military-grade temperature ranges compared to the commercial 74F series.
Replacement Considerations
Direct replacements include SN54F352J, SN54F352FK, and SN54F352FM. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength. Ensure the substitute part meets the same military qualification standards if required by the application.
