Description
CA-IF43232EN RS-232 Transceiver
The CA-IF43232E device consists of two line drivers, two line receivers, and a dual charge-pump circuit, which meets the requirements of the TIA/EIA-232-F and ITU V.28 standards and provides the electrical interface between an asynchronous communication controller and the serial-port connector. These devices have internal charge pumps with external capacitors could operate with 3-V to 5.5-V VCC supply. The CA-IF43232E devices operate at data signaling rates up to 250kbps and a maximum of 30-V/μs driver output (DOUT1/DOUT2) slew rate. These devices could provide standard narrow-body SOIC16 and small-footprint TSSOP16 packages, and are specified over extended industrial temperature range of –40°C to 125°C.
