HD293486

HD293486 Quadruple Dfferential Line Receivers With 3 State Outputs The HD293486 features quadruple Differential line receivers designed to meet the specs of EIA RS–422A and RS–423A. This device operates from a single 5 V power supply. When the enable input is low the associated outputs are in a high impedance state.

The above data were taken by the ∆VEB method mounting on a glass epoxy board (40 × 40 × 1.6 mm) of 10 % wiring density. 2. All voltage values except for differential input voltage are with respect to ground terminal. 3. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input. 4. The absolute maximum ratings are values...
