Product details

RS-232 interface in a 20-pin DIP — what this part is

The Maxim Integrated MAX233EPP+G36 is a full-duplex RS-232 transceiver packing two drivers and two receivers into a 20-pin DIP package. It handles serial communication at data rates up to 120 Kbps, drawing from a single 4.75 V to 5.25 V supply. The through-hole PDIP footprint suits legacy backplanes, industrial controllers, and bench equipment where socketed ICs simplify field replacement.

Receiver hysteresis — noise margin on long runs

With 500 mV of receiver hysteresis, the MAX233EPP+G36 rejects noise on cables up to a few metres in electrically noisy environments like motor drives or relay panels. That hysteresis margin reduces the chance of bit errors from coupled transients compared to parts with tighter thresholds.

Lifecycle and sourcing reality

No second-source or direct replacement is documented in the available records.

Frequently asked questions

What is the data rate of MAX233EPP+G36?

The MAX233EPP+G36 supports a maximum data rate of 120 Kbps. This is sufficient for standard RS-232 applications up to 115200 baud but will not handle higher-speed serial protocols.

Can MAX233EPP+G36 replace MAX232?

Both are 2/2 RS-232 transceivers, but the MAX233EPP+G36 is in a 20-pin DIP package while the classic MAX232 uses a 16-pin DIP. They are not pin-compatible — board layout changes are required. The MAX233 includes the charge-pump capacitors internally, saving two external capacitors versus the MAX232.

Can MAX233 run on 3.3V?

No. The MAX233EPP+G36 requires a 4.75 V to 5.25 V supply. It does not include a charge pump for 3.3 V operation — a 5 V rail is necessary.
