ISO1450DW

ISO1450DW Description

The ISO1450DW from Texas Instruments is a high-performance, isolated RS422/RS485 transceiver designed for robust communication in electrically noisy environments. Housed in a 16-SOIC package, this half-duplex transceiver integrates galvanic isolation (up to 3kVRMS) to protect sensitive circuitry from voltage spikes, ground loops, and EMI. It supports data rates up to 50Mbps, making it suitable for high-speed industrial networks. The device operates across dual supply voltages (1.71V–5.5V for logic-side and 3V–5.5V for bus-side), ensuring compatibility with mixed-voltage systems. With 30mV receiver hysteresis, it enhances noise immunity in challenging conditions.
