1 / 25 page  General Description The MAX14930–MAX14932 are a family of 4-channel, 2.75kVRMS and 3.75kVRMS digital isolators utilizing Maxim’s proprietary process technology. The MAX14130– MAX14131 are 4-channel 1kVRMS digital isolators in smaller footprint QSOP packages. For applications requiring 5kVRMS of isolation, see the MAX14934– MAX14936. The MAX14930–MAX14932 family transfers digital signals between circuits with different power domains at ambient temperatures up to +125°C. The MAX14930–MAX14932 family offers all three possible unidirectional channel configurations to accommodate any 4-channel design; including SPI, RS-232, RS-485, and digital I/O applications. For applications requiring bidirectional channels, such as I2C, see the MAX14933. Devices are available with data rates from DC up to 1Mbps, 25Mbps, or 150Mbps. Each device is also avail- able in either a default high or default low configuration. The default is the state an output goes to when its input is unpowered. See the Ordering Information and Selector Guide for the suffixes associated with each option. Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators. The MAX14930–MAX14932 are available in both a 16-pin wide body (10.3mm x 7.5mm) and narrow body (9.9mm x 3.9mm) SOIC package. The MAX14130–MAX14131 are available in a 16-pin (6mm x 5mm) QSOP package. All devices are rated for operation at ambient temperatures of -40°C to +125°C.
