HD75175 Quadruple Differential Line Receiver With 3 State Outputs ADE-205-593 (Z) 1st. Edition Dec. 2000 Description The HD75175 is a differential line receiver with three state outputs designed to meet the requirements of EIA standards RS-422A, RS-423A, RS-485 and several CCITT recommendations. The device features input sensitivity of ±200 mV over a common mode input voltage range of –12 V to +12 V. Each receiver features two active high enables, each common to two receivers.

The above date were taken by the ∆VBE method, mounting on a glass epoxy board (40 × 40 × 1.6 mm) of 10% wiring density. 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.

All typical values are at V CC = 5 V, Ta = 25°C. 2. Hysteresis is the difference between the positive going input threshold voltage V T+ and the negative going input threshold voltage VT–. 3. Not more than one output should be shorted at a time. 4. Refer to EIA standards RS-422A and RS-485 for exact conditions.
