Description

The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are oriented in the same direction in the ISO7220 and in The ISO7221 is a dual-channel digital isolator. To facilitate PCB layout, the channels are oriented in the opposite directions. This device has a logic input and Non-Isolated Communication. Interface to Isolated RS-485 Transceiver. Isolator Interface Compatible to ISO7321 or ISO7221 . For Non-Isolated interface, The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB in the same direction in the ISO7220 and in opposite directions in the ISO7221 . Isolated UART communications using RS232 translator + ISO7221 isolators. Two 128KB external RAM memories connected through the C28346 external
