Active RS-485 transceiver for industrial bus nodes
The MAX1487ESA+T is an active-production RS-485/RS-422 half-duplex transceiver from Analog Devices, rated for 2.5 Mbps signaling on a single 5V rail.
Industrial temperature grade and bus protocol fit
Half-duplex operation means the driver and receiver share the same pair of bus wires; the host MCU controls the driver enable pin to switch between transmit and receive. The 4.75V to 5.25V supply range is compatible with legacy 5V logic systems and industrial backplanes that still run a 5V rail.
Package and board integration
Surface-mount assembly suits automated pick-and-place lines; the tape-and-reel variant (T suffix) feeds directly into the placement machine without reel changeovers.
