+5V Powered RS-232
Features
Transmitters/Receivers
• Meets All RS-232E and V.28 Specifications
The HIN231-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 family of devices offer a wide variety of
RS-232 transmitter/receiver combinations to accommodate
various applications (see Selection Table).
• 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
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.
• Three-State TTL/CMOS Receiver Outputs
• Multiple Drivers
-
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
- 3kΩ to 7kΩ Input Impedance
- 0.5V Hysteresis to Improve Noise Rejection
Applications
• Any System Requiring RS-232 Communication Ports
- Computer - Portable, Mainframe, Laptop
- Peripheral - Printers and Terminals
- Instrumentation
- Modems
