Half-duplex RS-485/RS-422 transceiver in 8-DIP
The MAX3072EEPA+ is a half-duplex transceiver supporting both RS-422 and RS-485 protocols, with one driver and one receiver integrated in a single 8-pin DIP package. The 100 mV of receiver hysteresis provides noise margin on long cable runs where ground potential differences and common-mode noise degrade signal integrity. For a 250kbps link at 4000 feet, that hysteresis band filters out the reflected-edge ringing that would otherwise cause bit errors at the receiver input.
Through-hole 8-DIP for prototyping and legacy support
Housed in an 8-DIP (0.300", 7.62mm) through-hole package with a supplier device package designation of 8-PDIP, this transceiver is a natural fit for breadboard prototyping, socketed evaluation, or designs that require hand-solderable through-hole assembly. The 0.100-inch pin pitch and standard DIP footprint mean it drops into existing RS-485 layouts without a board spin. For applications that push toward the +85°C upper bound, the 3V minimum supply headroom ensures the driver output differential voltage stays above the RS-485 threshold across the full temperature sweep.
