Product Summary
The SN75C3223DBR is a differential data line transceiver in the trade-standard footprint of the SN75C3223DBR with built-in protection against high-energy noise transients. This feature of SN75C3223DBR provides a substantial increase in reliability for better immunity to noise transients coupled to the data cable over most existing devices. Use of SN75C3223DBR provides a reliable low-cost direct-coupled (with no isolation transformer) data line interface without requiring any external components.
