Functions :

The MAX220 Thru MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available.

These parts are especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5µW. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.

Saves Board Space

1. Integrated Charge Pump Circuitry
• Eliminates the Need for a Bipolar ±12V Supply
• Enables Single Supply Operation from +5V Supply
2. Integrated Capacitors (MAX223, MAX233, MAX235, MAX245–MAX247) Saves Power for Reduced Power Requirements
3.  5μW Shutdown Mode

RS-232 Receivers

EIA/TIA-232E and V.28 specifications define a voltage level greater than 3V as a logic 0, so all receivers invert. Input thresholds are set at 0.8V and 2.4V, so receivers respond to TTL level inputs as well as EIA/TIA-232E and V.28 levels. The receiver inputs withstand an input overvoltage up to ±25V and provide input terminating resistors with nominal 5kΩvalues. The receivers implement Type 1 interpretation of the fault conditions of V.28 and EIA/TIA-232E.
