RS-422/RS-485 bus interface, 250 kbps, full duplex
The MAX3157CAI+T is a single-channel RS-422/RS-485 transceiver in a 28-pin SSOP package, delivering full-duplex communication at 250 kbps over a single twisted pair per direction.
Supply and temperature envelope
This suits indoor equipment, instrumentation, and control panels where the ambient stays within office or light-industrial limits.
Housed in a 28-SSOP (0.209", 5.30 mm width) — the supplier device package is 28-SSOP. The 0.65 mm pitch requires a standard SSOP-28 footprint; no thermal pad or exposed paddle. Available in Tape & Reel (TR) or Cut Tape (CT) for prototyping. Surface-mount assembly reflow profile follows standard SSOP guidelines.
