Surface-mount 16-SOIC (0.154" body width, 3.90 mm). Standard footprint, no fine-pitch reflow tricks. Tube delivery — if your pick-and-place feeds from tape, factor in a transfer step or order the tape-reel variant.
Marked Active on the lifecycle record — no NRND or EOL flags. ROHS3 compliant.
The MAX202CSE+ is a compatible variant within the same family — same pinout and function, but check the temperature grade if your environment exceeds 70°C. For a second-source option, the SP202E from Sipex (now Exar) is a direct functional equivalent, though verify the receiver hysteresis and supply range against your design margin.
Yes, like all MAX202-style transceivers, it needs four external charge-pump capacitors (typically 0.1 µF to 1 µF) to generate the RS-232 voltage levels. The datasheet layout shows the recommended values and placement.
Standard 16-pin SOIC pinout for the MAX202 family: pins 1-4 and 6-7 are the charge-pump capacitor connections, pins 8-9 are the receiver outputs (R1OUT, R2OUT), pins 10-11 are the receiver inputs (R1IN, R2IN), pins 12-13 are the driver inputs (T1IN, T2IN), pins 14-15 are the driver outputs (T1OUT, T2OUT), pin 16 is VCC, and pin 5 is GND.
