| RS232DI
Complete, +5V, Isolated, Dual RS232 Transceiver
| GENERAL DESCRIPTION
The RS232DI is a complete, electrically isolated, dual
RS-232 Transceiver that requires no external components. The
device includes isolation for both the communications lines
as well as the single +5V power supply.
Isolation for the device is 2500Vrms for one minute which
makes it ideal for applications with high transient voltages
and different ground potentials.
The RS232DI comes in an encapsulated 40 pin DIP package.
