Product details

RS-232 transceiver for 5V serial links

It handles asynchronous serial communication up to 120 kbps, with the charge-pump generating the ±10 V swing from a single 5 V supply. The 500 mV receiver hysteresis provides noise margin on the bus, useful in industrial environments where cable runs pick up interference.

Supply and interface fit

The 120 kbps data rate covers legacy UART speeds (9600, 19200, 38400 baud) and most RS-232 applications below 115.2 kbps.

Frequently asked questions

Where can I buy MAX232IDW?

The MAX232IDW is available to order through independent distribution.

Is MAX232IDW compatible with 3.3V systems?

No. For 3.3 V RS-232, consider the MAX3232 family.

How does MAX232IDW compare to MAX3232?

The MAX232IDW is limited to 5 V and 120 kbps but is otherwise pin-compatible in the same 16-SOIC footprint.
