HD26LS32A Quadruple Differential Line Receivers With 3 State Outputs REJ03D0296–0200Z (Previous ADE-205-578 (Z)) Rev.2.00 Jul.16.2004 Description The HD26LS32A features quadruple line receivers designed to meet the specs of EIA standard RS-422A and RS-423. This device operates from a single 5 V power supply. The enable function is common to all four receivers and offers a choice of active high or active low input. Fail safe design ensures that if the inputs are open, the outputs will always be high.

All voltage values except for differential input voltage are with respect to network ground terminal. 2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input. 3. The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time.
