The HIN202, HIN206, HIN207, HIN208, HIN211, HIN213 family of RS-232 transmitters/receivers interface circuits meet all ElA RS-232E and V.28 specifications, and are particularly suited for those applications where ±12V is not available. They require a single +5V power supply and feature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The family of devices offers a wide variety of RS-232 transmitter/receiver combinations to accommodate various applications (see Selection Table).

The HIN206, HIN211 and HIN213 feature a low power shutdown mode to conserve energy in battery powered applications. In addition, the HIN213 provides two active receivers in shutdown mode allowing for easy "wakeup" capability.

The drivers feature true TTL/CMOS input compatibility, slew rate-limited output, and 300Ω power-off source impedance. The receivers can handle up to ±30V input, and have a 3kΩ to 7kΩ input impedance. The receivers also feature hysteresis to greatly improve noise rejection.

Design Tip

I see many manufacturers offer "+/-15kV ESD Protected" (or "High ESD") products. Does this mean that they all have the same level of protection?
