The ISO7421D from Texas Instruments is a 2-channel digital isolator utilizing capacitive coupling technology. It provides robust isolation with a withstand voltage of 2500Vrms and a high Common Mode Transient Immunity (CMTI) of 25kV/µs.
This general-purpose isolator supports unidirectional channels and operates at data rates up to 1Mbps. Key electrical characteristics include a typical propagation delay of 9ns and a maximum pulse width distortion of 3.7ns. The device is designed for a wide operating temperature range of -40°C to 125°C.
Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount form factor, the ISO7421D is suitable for various industrial and communication applications requiring reliable signal isolation. It features low power consumption with a typical current draw of 1.5mA per channel.
