HD26C32A Datasheet | Hitachi Semiconductor

Description The HD26C32A provides differential line receivers which realize low power dissipation by CMOS process. The device has four receivers which meet the requirements of EIA standard RS-422A and RS-423A in a 16 pin package. The enable function is mon to all four receivers and offers a choise of active high or active low inputs. Fail safe design ensures that if the inputs are open the outputs will always be high.

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. 2. All voltage values except for differential input voltage are with respect to network ground terminal. 3. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input.
