The HIN232-HIN241 family of RS-232 transmitters/receivers
interface circuits meet all ElA RS-232E and V.28 specifications,
Features
• Meets All 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
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
• Requires Only Single +5V Power Supply
- (+5V and +12V - HIN239)
• High Data Rate. . . . . . . . . . . . . . . . . . . . . . . . . . . 120kbps
• Onboard Voltage Doubler/Inverter
• Low Power Consumption
transmitter/receiver combinations to accommodate various
applications (see “Selection Table” on page 1).
The drivers feature true TTL/CMOS input compatibility,
slew-rate-limited output, and 300 power-off source
impedance. The receivers can handle up to ±30V, and have
a 3k to 7k input impedance. The receivers also feature
hysteresis to greatly improve noise rejection.
• Low Power Shutdown Function
• Three-State TTL/CMOS Receiver Outputs
• Multiple Drivers
- ±10V Output Swing for 5V lnput
- 300 Power-Off Source Impedance
- Output Current Limiting
- TTL/CMOS Compatible
- 30V/µs Maximum Slew Rate
• Multiple Receivers
- ±30V Input Voltage Range
- 3k to 7k Input Impedance
- 0.5V Hysteresis to Improve Noise Rejection
• Pb-free Available (RoHS compliant)
Applications
• Any System Requiring RS-232 Communication Ports
- Computer - Portable, Mainframe, Laptop
- Peripheral - Printers and Terminals
- Instrumentation
- Modems
