HD29413 Quadruple Differential Line Receivers With 3 State Outputs ADE-205-582 (Z) 1st. Edition Dec. 2000 Description The HD29413 features quadruple differential line receivers designed to meet the spec of EIA RS422AandRS-423A. The device operates from a single 5 V power supply. The enable function is common to all four receivers and offer a choice of active high or active low inputs. (Complementary output enable input.) Faile safe circuit guarantees the outputs always at the high level when the inputs are open.

All voltage values except for differential input voltage are with respect to ground terminal. 2. VIC = 1/2 (VIA + VIB) |VID| = |VIA – VIB| 3. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input. 4. 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.
