HD26LS32A Quadruple Differential Line Receivers With 3 State Outputs ADE-205-578 (Z) 1st. Edition Dec. 2000 Description The HD26LS32A features quadruple line receivers designed to meet the specs of EIA standard RS-422A and RS-423. This device operates from a single 5 V power supply. The enable function is common to all four receivers and offers a choice of active high or active low input. Fail safe design ensures that if the inputs are open, the outputs will always be high.

All voltage values except for differential input voltage are with respect to network ground terminal. 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,VIC = 0. 2. Hysteresis is the differential between the positive going input threshold voltage and the negative going input threshold voltage. 3. Not more than one output should be shorted at a time. 4 HD26LS32A Switching Characteristics (VCC = 5 V, Ta = 25°C) Item Symbol Min Typ Max Unit Conditions Propagation Delay Time t PLH — 20 35 ns CL = 15 pF t PHL — 22 35 t ZH — 17 22 ns CL = 15 pF t ZL — 20 25 t HZ — 21 30 ns CL = 5 pF t LZ — 30 40 Output Enable Time Output Disable Time 5 HD26LS32A 1. tPLH, tPHL Test circuit VCC Input Output 2 kΩ Pulse Generator CL 5 kΩ 2V Waveforms 2.5 V Input A 0V 0V –2.5 V 2.5 V Input B 0V 0V –2.5 V t PLH t PHL VOH Output 1.3 V 1.3 V VOL 6 HD26LS32A 2. tHZ, tZH Test circuit VCC Output 2 kΩ S1 2.5 V CL 5 kΩ Input Pulse Generator 2V Waveforms 3V Enable G 1.3 V 1.3 V 0V 3V 1.3 V 1.3 V Enable G 0V S1 : Open t ZH Output 1.3 V S1 : Closed t HZ 0.5 V VOH 1.4 V 0V 7 HD26LS32A 3. tLZ, tZL Test circuit VCC Output 2 kΩ –2.5 V CL 5 kΩ Input Pulse Generator S2 2V Waveforms 3V Enable 1.3 V 1.3 V 0V 3V 1.3 V 1.3 V Enable G 0V S2 : Open t ZL S2 : Closed t LZ VOH Output 1.4 V 1.3 V 0.5 V Notes: 1. 2. 3. 4. 8 The pulse generator has the following characteristics: PRR = 1 MHz, 50% duty cycle, tr ≤ 6 ns, tf ≤ 6 ns, Zout = 50Ω.
