HD26LS32

www.DataSheet4U.com HD26LS32 Quadruple Differential Line Receivers With 3 State Outputs ADE-205-577 (Z) 1st. Edition Dec. 2000 Description The HD26LS32 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.
