MAX14931CAWE+

The MAX14930–MAX14932 are a family of 4-channel 2.75kVRMS digital isolators utilizing Maxim’s proprietary process technology. The MAX14130–MAX14131 are 4-channel 1kVRMS digital isolators in smaller footprint QSOP packages. The MAX14930–MAX14932 family transfers digital signals between circuits with different power domains at ambient temperatures up to +125℃. 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. Devices are available with data rates from DC up to 1Mbps, 25Mbps, or 150Mbps. Each device is also available in either a default high or default low configuration. 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 (10.3mmx7.5mm) and narrow body (9.9mm x 3.9mm) SOIC package. The MAX14130–MAX14131 are available in a 16-pin (6mmx5mm) QSOP package. All devices are rated for operation at ambient temperatures of -40℃ to +125℃.
