Texas Instruments MAX232N RS-232 Transceiver 5V 16-Pin PDIP
Texas Instruments MAX232N RS-232 transceiver, 5V single supply, 16-pin PDIP. Converts RS-232 and TTL/CMOS logic levels for serial communication.
Texas Instruments MAX232N RS-232 Transceiver 5V is a dual driver and receiver integrated circuit for TIA/EIA-232-F (RS-232) serial communication from a single 5V power supply, supplied in a 16-pin PDIP package.
Overview
The MAX232N includes an internal capacitive voltage generator, removing the need for external high-voltage power supplies. Each of its two receivers converts RS-232 signal inputs into standard 5V TTL/CMOS logic levels, with a typical threshold of 1.3V and 0.5V of hysteresis for improved noise immunity. The receivers can accept inputs of up to ±30V. The two drivers convert TTL/CMOS logic signals back into compliant RS-232 output levels, making the device suitable for connecting legacy serial equipment and modernising serial interfaces.
