intersil HIN232 HIN236 HIN237 HIN238 HIN239 HIN240 HIN241 handbook(1)
The HIN232-HIN241 family of RS-232 transmitters/receivers interface circuits meet all EIA RS-232E and V.28 specifications and are particularly suited for 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 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.

Questions answered in these manuals
What power supply is required for the HIN232-HIN241 family?
They require a single +5V power supply, except for the HIN239 which also requires +7.5V to 13.2V.
From: intersil HIN232 HIN236 HIN237 HIN238 HIN239 HIN240 HIN241 handbook(1)
Do these devices require external capacitors?
Yes, they feature onboard charge pump voltage converters that require external capacitors to generate the necessary voltage levels.
