ISO7760DBQ

ISO7760DBQ Description

The ISO7760DBQ from Texas Instruments is a high-performance, 6-channel digital isolator designed for robust signal isolation in demanding industrial and automotive applications. Utilizing capacitive coupling technology, it delivers reliable isolation up to 3000Vrms with a wide supply voltage range of 2.25V to 5.5V, making it versatile for mixed-voltage systems. This unidirectional isolator supports a 100Mbps data rate and features ultra-low propagation delay (16ns max) and minimal pulse width distortion (4.9ns max), ensuring high-speed signal integrity. Its 85kV/µs common-mode transient immunity (CMTI) enhances noise immunity in electrically noisy environments. Packaged in a 16-pin SSOP tube, it is RoHS3 compliant and rated for MSL 2 (1 year) moisture sensitivity.
