SKU: MAX231MAXIMDS2000 Category: Brand:

Description

The MAX231 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 5uW.

The MAX231 contain four sections: dual charge-pump DC-DC voltage converters, RS-232 drivers, RS-232 receivers, and receiver and transmitter enable control inputs.

APPLICATIONS:
– Portable Computers
– Low-Power Modems
– Interface Translation
– Battery-Powered RS-232 Systems
– Multidrop RS-232 Networks

FEATURES:
– Superior to Bipolar
– Operate from Single +5V Power Supply (+5V and +12V – MAX231)
– Meet All EIA/TIA-232E and V.28 Specifications
– Multiple Drivers and Receivers
– 3-State Driver and Receiver Outputs
