GENERAL DESCRIPTION
Dual high speed 232 isolation transceiver TD302D232H/
TD502D232H series are integrated isolation power, Signal
isolation chip and RS232 transceiver chip in one of the RS232
interface integrated isolation module.
The main function of Products is to switch from logic level to
232 protocols level, achieve signal isolation. The product is with
constant-voltage source isolation power. It can achieve 2500
VDC electrical isolation, and has the function of ESD protection.
Products can be easily embedded in the user equipm ent,
achieve function of 232 protocols network connection easily.
