ISO7240C
Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.
This Texas Instruments datasheet covers the ISO7240, ISO7241, and ISO7242 families of high-speed quad digital isolators. The document defines their scope as blocking high voltage and isolating grounds to protect sensitive circuitry from noise in industrial and computer applications. Key parameters include 25 or 150 Mbps signaling rates, 4kV ESD protection, operation over a -40°C to 125°C temperature range, and supply voltages ranging from 2.8 V to 5 V. Specific variants offer TTL or CMOS input thresholds, with the ISO7240CF adding failsafe output and input disable functions.
