The MAX3078EIN with DIP-8 is a RS-485/RS-422 ICs ROHS manufactured by HGSEMI. It is designed for data communications over twisted-pair, shielded cable in noisy environments. This IC integrates the physical layer of the RS-485/RS-422 protocols into a single IC, eliminating the need for connection of external line-termination resistors and providing bus signal line common-mode voltage control in a space-saving package.This device features full-duplex operation, a 1000 Vrms rated isolation barrier between the transmit/receive Pins and the control bus Pins, low-power sleep mode with very low power consumption, needle-driver logic outputs for easy voltage level conversion, surge immunity up to 80 V/µs, and wide operating temperature range. It is available in DIP-8 package and is RoHS compliant.
