XR32430EHCR-F

Exar XR32430/XR32431 3-Driver/5-Receiver Intelligent RS-232 Transceivers use an internal high-efficiency charge-pump power supply that requires only four 0.1F capacitors in 3.3V operation. The XR32431 features a variable low voltage logic interface, down to 1.65V. These products are intended for portable or hand-held applications such as notebook and palmtop computers. The XR32430EB and XR32431EB devices feature slew-rate limited outputs for reduced crosstalk and EMI. The XR32430EH and XR32431EH devices are optimized for mid speed applications, with data rates up to 460Kbps. The XR32430EU and XR32431EU devices are optimized for high speed designs with data rates up to 1Mbps and meet the demands of high speed RS-232 applications.
