AI Overview
The
ISO1412BDW is a 5kVRMS isolated RS-485/RS-422 transceiver from Texas Instruments, specifically a 1/1 transceiver with 12Mbps data rate in a 16-SOIC package.Here are the best alternatives and equivalent parts based on functional, electrical, and physical specifications:
Direct Replacements (Same Function & Package)
- ISO1412BDWR (Texas Instruments): This is the exact same component (ISO1412B) in tape-and-reel (R) packaging.
- ISO1412DW (Texas Instruments): Identical functional specifications but may differ in basic vs. reinforced isolation ratings (check datasheet).
Closest Functionally Similar Parts (TI Portfolio)
These parts belong to the same ISO14xx family, offering similar high common-mode transient immunity (100kV/µs) and ESD protection:
- ISO1410BDW: Similar isolated transceiver, typically optimized for different configurations (e.g., higher speed or different directionality).
- ISO1430BDW: 3/0 channel configuration, suitable if 1/1 directionality is not strictly required and 3 lines in one direction are needed.
- ISO1432BDW: 2/1 channel configuration.
Alternative Manufacturer Options (Non-TI)
Other manufacturers offer pin-compatible or functional alternatives for isolated RS-485, although they may not be "drop-in" replacements without checking pinout nuances:
- Analog Devices (ADM系列): Look for ADM2582E/ADM2587E (integrated power) or ADM2682E/ADM2687E.
- Silicon Labs (Si86xx series): Often paired with a standard RS-485 transceiver.
Key Specifications to Consider
When selecting an alternative, ensure the replacement meets these specs:
- Isolation: 5000VRMS (Minimum)
- Data Rate: Up to 12Mbps (or 50Mbps depending on version)
- Package: Wide-body SOIC-16 (DW)
- Voltage: 1.71V to 5.5V logic-side, 3V to 5.5V bus-side.
Note: The ISO1412BDW is in stock at major distributors like Mouser and DigiKey.
