ICL232

+5V Powered, Dual RS-232

Transmitter/Receiver

The ICL232 is a dual RS-232 transmitter/receiver interface

circuit that meets all ElA RS-232C and V.28 specifications. It

requires a single +5V power supply, and features two

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 300

Ω power-off source impedance.

The receivers can handle up to +30V, and have a 3k

Ω to

7k

Ω input impedance. The receivers also have hysteresis to

improve noise rejection.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
