Texas Instruments ISO6163 Six-Channel 3/3 Digital Isolators

These devices are designed with low power consumption, high electromagnetic immunity, and low emissions while isolating CMOS or LVCMOS digital I/O signals such as GPIOs, SPI (ADC, DAC, other peripherals), UART, RS-485, RS-232, and CAN. Each channel has a logic input and output buffer separated by TI’s proprietary silicon dioxide (SiO₂) isolation barrier.

The TI ISO6163 device has three forward channels and three reverse-direction channels. It provides two low-speed data channels with bidirectional automatic enable control functionality. The low-speed control channels automatically enable the high-speed channels when needed or turn them off (outputs high impedance) to further reduce power consumption when the system does not require high-speed data transfer. In the event of input power or signal loss, the default output level is high for devices without the suffix F and low for devices with the suffix F.
