+Stresses beyond those listed under "absolute maximum ratings"may cause permanent
damage to the device. These are stress ratings only, and functional operation of the device
at these or any other conditions beyond those indicated under"recommended operating
conditions"is not implied. Exposure to absolute-maximum-rated conditions for extended
periods may affect device reliability.
NOTES:1.All voltage values, except differential input voltage, are with respect to network
            ground terminal.
            2.Differential input voltage is measured at the noninverting terminal with respect
            to the inverting terminal.
            3.Maximum power dissipation is a function of T_J (max), _JA, and T_A. The maximum
            allowable power dissipation at any allowable ambient temperature is P_D
            = (T_J (max)-T _A)/_JA. Operating at the absolute maximum T_J of 150 can affect
           reliability.
            4.The package thermal impedance is calculated in accordance with JESD 51-7.

Description

The SN75ALS181 is a differential driver and receiver pair designed for bidirectional data communication on multipoint us transmission lines. The design provides for balanced transmission lines and meetsTIA/EIA-422-B and TIA/EIA-485-A, nd CCITT recommendations V.10, V.11, X.26, and X.27.

The SN75ALS181 combines a 3-state differential line driver and a differential-input line receiver that operate from a ngle 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, that can be connected together externally to function as a direction control. The driver differential outputs and the receiver differential inputs e connected to separate pins for greater flexibility and are designed to offer minimum loading to the bus when the driver is disabled or V_CC = 0. These ports feature wide positive and negative common-mode voltage changes, making the ice suitable for party-line applications.
