MAX232 SLLS047N – FEBRUARY 1989 – REVISED FEBRUARY 2024 MAX232 Dual EIA-232 Drivers and Receivers 1 Features Meets or exceeds TIA/EIA-232-F and ITU recommendation V.28 Operates from a single 5V power supply with 1µF charge-pump capacitors Operates up to 120kbit/s Two drivers and two receivers ±30V Input levels Low supply current: 8mA typical ESD protection exceeds JESD 22 – 2000V Human-body model (A114-A) Upgrade with improved ESD (15kV HBM) and 0.1µF charge-pump capacitors is available with the MAX202 device 2 Applications TIA/EIA-232-F Battery-powered systems Terminals Modems Computers 3 Description The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/ EIA-232-F voltage levels from a single 5V supply. Each receiver converts TIA/EIA-232-F inputs to 5V TTL/CMOS levels. These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5V, and can accept ±30V inputs. Each driver converts TTL/ CMOS input levels into TIA/EIA-232-F levels.
