HIN241E

The HIN202E-HIN241E family of RS-232 transmitters/receivers interface circuits meet all ElA high-speed RS-232E and V.28 specifications, and are particularly suited for those applications where ± 12V is not available. A redesigned transmitter circuit improves data rate and slew rate, which makes this suitable for ISDN and high speed modems. The transmitter outputs and receiver inputs are protected to ± 15kV ESD (Electrostatic Discharge).Theyrequireasingle+5Vpowersupplyandfeature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The HIN205E and HIN235E require no external capacitors and are ideally suited for applications where circuit board space is critical. The family of devices offers a wide variety of high-speed RS-232 transmitter/receiver combinations to accommodate various applications (see Selection Table).

The HIN205E, HIN206E, HIN211E, HIN213E, HIN235E, HIN236E,andHIN241Efeaturealowpowershutdownmodeto conserve energy in battery powered applications. In addition, the HIN213E provides two active receivers in shutdown mode allowing for easy "wakeup" capability. The drivers feature true TTL/CMOS input compatibility, slew rate-limitedoutput,and300Ω power offsourceimpedance.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.
