RS-485 Transceiver
V660x is a RS-485 transceiver with low power consumption, ±15KV ESD protection, and it is completely fulfilled EIA/TUA-485 standards. V660x series are included with a driver and a receiver, and it has the high driving capability allowing to transceivers on the same communication bus. V6602 and V6602H embedded low-slew-rate driver which can reduce EMI and reflections caused by inappropriate terminal matching. It can realize the error-free data transmission up to 500Kbps. V6603 and V6603H can support the high-speed communication, and the maximum communication speed is up to 2Mbps. V6602H and V6603H embedded LDO which can support the maximum input voltage up to 24V, and the output voltage of LDO up to 5.0V which can support driving capacity up to 100mA.
