These Texas Instruments MAX232N devices are designed to convert between TTL voltage levels (0 to 5V) and TIA/EIA-232-F levels (±30V). They operate from a single 5VDC power supply with charge-pump capacitors for situations where multiple supply voltages are not available such as battery powered or compact systems. * Meets or exceeds TIA/EIA-232-F and ITU recommendation V.28 * Operates up to 120kbit/s * ±30V input levels * Low supply current * DIL-16
