HD29C3486 Quadruple Differential Line Receivers With 3 State Outputs ADE-205-586 (Z) 1st. Edition Dec. 2000 Description The HD29C3486 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 RS423A in a 16 pin package. The circuit provides two high enable terminals and each of the terminals can control two receivers. Fail safe design ensures that if the inputs are open the outputs will always be high. Features • • • • • • • • • Low power dissipation with CMOS process Meets EIA standard RS-422A/423A Input sensitivity: ±0.2 V (In the range of ±7 V of common mode input voltage) Propagation delay time: 19 ns typ Input hysteresis width: 60 mV typ Three state outputs Differential inputs are includes fail safe circuit Power up and power down protection Pin to pin compatible with HD293486 HD29C3486 Pin Arrangement IN A1 1 16 VCC IN A2 2 15 IN B1 OUT A 3 14 IN B2 Enable A, C 13 OUT B 4 OUT C 5 12 Enable B, D IN C2 6 11 OUT D IN C1 7 10 IN D2 GND 8 9 IN D1 (Top view) Function Table Differential Input Enable Output VID ≥ VTH or OPEN H H VTL < VID < VTH H ?

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.
