Introduction
The MAX14934–MAX14936 are a family of four-channel, 5kVRMS digital isolators utilizing Maxim’s proprietary process technology. The MAX14934–MAX14936 family transfers digital signals between circuits with different power domains at ambient temperatures up to +125℃. The MAX14934–MAX14936 family offers all three possible unidirectional channel configurations to accommodate any four-channel design, including SPI, RS-232, RS-485, and large digital IO modules. 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 MAX14934–MAX14936 are available in a 16-pin wide body (10.3mmx7.5mm) SOIC package. All devices are rated for operation at ambient temperatures of -40℃ to +125℃.
