ISO7740FDBQR Description

Short technical summary and product information.

The Texas Instruments ISO7740FDBQR is a robust, 4-channel digital isolator with unidirectional signal flow. It operates at data rates up to 100Mbps and provides a withstand isolation voltage of 3000Vrms, with surge capabilities up to 12.8kVpk. This device features a high Common Mode Transient Immunity (CMTI) of 85kV/µs, ensuring signal integrity in noisy environments.

 

Designed for surface mounting, the ISO7740FDBQR comes in a 16-SSOP package. It supports a wide operating temperature range from -55°C to 125°C and operates with supply voltages between 2.25V and 5.5V. The isolator is suitable for applications requiring general-purpose isolation, supporting protocols like GPIO and PWM.

 

Key electrical characteristics include a typical propagation delay of 10.7ns and a maximum part-to-part output skew of 4.4ns. Low power consumption is achieved with a typical current draw of 0.775mA per channel at DC and 1.375mA per channel at 1Mbps. The device is certified by CQC, CSA, DIN, and TUV, meeting both basic and reinforced isolation standards.
