The ADM3202ARWZ is a full-duplex RS232 transceiver with two drivers and two receivers (2/2), operating from a single 3V to 5.5V supply. It handles serial data at 460 kbps, which is roughly four times the rate of the classic MAX232 — useful for designs that need to push more throughput over a legacy RS232 line. The 400 mV receiver hysteresis gives clean edge detection on noisy cables, which is the kind of margin that keeps a UART from seeing false start bits on a long run.
Supply voltage flexibility and 3.3V operation
The 3V to 5.5V supply range covers both legacy 5V RS232 rails and modern 3.3V-only systems. A common design-in question is whether this part works at 3.3V — yes, it does, and at that rail voltage the 460 kbps data rate is still specified, so you are not trading speed for lower voltage.
Housed in a 16-SOIC package with 0.295-inch (7.50 mm) body width, the ADM3202ARWZ is a surface-mount part that fits a standard SOIC-16 footprint.
