The MAX202CD is an active-production RS-232 transceiver from Maxim Integrated, still a solid choice for legacy serial links or new designs that need a reliable 5 V interface.
Receiver hysteresis is 500 mV, which gives clean edge detection on noisy RS-232 lines without extra external filtering.
The MAX202CD is functionally similar to the MAX232 — both are 5 V RS-232 transceivers with 2/2 drivers/receivers in a 16-SOIC package. The MAX202CD typically offers a slightly higher data rate (120 kbps vs 120 kbps typical for MAX232) and 500 mV receiver hysteresis. In most designs it is a drop-in replacement, but verify the pinout against your specific MAX232 variant; the MAX202CD uses the same industry-standard 16-SOIC pin arrangement as the MAX232 family.
