+5V Powered RS-232
Features
Transmitters/Receivers
• Meets All RS-232E and V.28 Specifications
The HIN230-HIN241 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 (except
HIN231 and HIN239) and feature onboard charge pump
voltage converters which generate +10V and -10V supplies
from the 5V supply. The HIN233 and HIN235 require no
external capacitors and are ideally suited for applications where
circuit board space is critical. The family of devices offer a wide
variety of RS-232 transmitter/receiver combinations to
• Requires Only Single +5V Power Supply
- (+5V and +12V - HIN231 and HIN239)
• High Data Rate. . . . . . . . . . . . . . . . . . . . . . . . . . . 120kbps
• HIN233 and HIN235 Require No External Capacitors
• Onboard Voltage Doubler/Inverter
• Low Power Consumption
• Low Power Shutdown Function
accommodate various applications (see Selection Table).
• Three-State TTL/CMOS Receiver Outputs
• Multiple Drivers
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, and have a 3kΩ to 7kΩ
input impedance. The receivers also feature hysteresis to
greatly improve noise rejection.
- ±10V Output Swing for 5V lnput
- 300Ω Power-Off Source Impedance
- Output Current Limiting
- TTL/CMOS Compatible
- 30V/µs Maximum Slew Rate
• Multiple Receivers
- ±30V Input Voltage Range
