MAX231 Datasheet | Maxim Integrated

Description The MAX220- MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 munications interfaces, particularly applications where ±12V is not available. The MAX225, MAX233, MAX235, and MAX245/MAX246/ MAX247 use no external ponents and are remended for applications where printed circuit board space is critical. The MAX220-MAX249 are offered in 26 different packages with temperatures from 0 to +70°C up to -55°C to +125°C. See ordering information table at the end of the data sheet for all package and temperature options. Applications - - Interface Translation - - Multidrop RS-232 Networks - - Portable Diagnostics Equipment Benefits and Features Saves Board Space - - Integrated Charge Pump Circuitry - Eliminates the Need for a Bipolar ±12V Supply - Enables Single Supply Operation from +5V Supply - - Integrated Capacitors (MAX223, MAX233, MAX235, MAX245- MAX247) Saves Power for Reduced Power Requirements - - 5μW Shutdown Mode Ordering Information and Selection Table appears at end of data sheet.
