Part Number : MAX232, MAX232CPE
Function : +5V-Powered, Multichannel RS-232 Driver / Receiver
Package : DIP 16 Pin
Manufacturers : Maxim Integrated
This is Multichannel RS-232 Driver / Receiver.
The MAX220, MAX232 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.
The MAX220 thru 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.
The typical driver output voltage swing is ±8V when loaded with a nominal 5kΩRS-232 receiver and VCC=+5V. Output swing is guaranteed to meet the EIA/TIA-232E and V.28 specification, which calls for ±5V minimum driver output levels under worst-case conditions. These include a minimum 3kΩload, VCC= +4.5V, and maximum operating temperature. Unloaded driver output voltage ranges from (V+ -1.3V) to (V- +0.5V).
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.
