FT232H SINGLE CHANNEL HI-SPEED USB TO MULTIPURPOSE UART/FIFO IC
Datasheet Version 1.2
Clearance No.: FTDI #199
4.3.2 RS422 Configuration
Figure 4.2 illustrates how the FT232H can be configured as a RS422 interface.
Figure 4.2 Dual RS422 Configuration
In this case the FT232H is configured as UART operating at TTL levels and a level converter device (full
duplex RS485 transceiver) is used to convert the TTL level signals from the FT232H to RS422 levels. The
PWREN# signal is used to power down the level shifters such that they operate in a low quiescent current
when the USB interface is in suspend mode.
