ISO7740FQDBQRQ1

ISO7740FQDBQRQ1 Description

The ISO7740FQDBQRQ1 from Texas Instruments is a high-performance, quad-channel digital isolator designed for automotive and industrial applications requiring robust signal isolation. Utilizing capacitive coupling technology, it delivers reliable isolation up to 2500Vrms with a data rate of 100Mbps, making it suitable for high-speed communication interfaces. The device operates over a wide supply voltage range (2.25V to 5.5V), ensuring compatibility with diverse system requirements. Its unidirectional channels (4 inputs on Side 1, 0 on Side 2) provide deterministic signal integrity, while features like 85kV/µs common-mode transient immunity (CMTI) and low propagation delay (16ns max) enhance noise immunity and timing precision. Packaged in a 16-pin SSOP and compliant with AEC-Q100 automotive standards, it meets stringent reliability demands.
