RS-232 Transceivers Provide Adjustable Low-Voltage Interface

RS-232 Transceivers Provide Adjustable Low-Voltage Interface
Exar Corp.

The XR32220, XR32430, and XR32431 family of RS-232 (EIA/TIA-232) transceivers operate from 3V to 5.5V supplies and include an adjustable low voltage logic interface. In many applications, RS-232 transceivers interface with UARTs, MCUs and other logic devices operating from supplies less than 3.3V. The XR32220 and XR32431 feature a low voltage logic pin (VL) range from 1.65V to 5.5V. The adjustable low voltage interface eliminates the need for a level shifter/translator between the transceiver and UART or MCU. The XR32220, XR32430 and XR32431 are available in RoHS compliant, green/halogen free, 4 mm x 4 mm QFN (XR32220) and 5 mm x 5 mm QFN (XR32430/31) packages. For more details, visit
