Description

The HIN235CP is a member of the HIN230-HIN241 family of RS-232 transmitters/receivers interface circuits. It meets all ElA RS-232E and V.28 specifications and is especially suitable for applications where ±12V is not available. This electronic component requires only a single +5V power supply (except HIN231 and HIN239) and features onboard charge pump voltage converters, which generate +10V and -10V supplies from the 5V supply. The HIN233 and HIN235 models require no external capacitors and are ideal for space-constrained circuit board designs. The family of devices offers a wide range of RS-232 transmitter/receiver combinations to meet various application needs.
