HD26LS32A
Quadruple Differential Line Receivers With 3 State Outputs
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.

Notes: 1. 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.

Notes: 1. All typical values are at VCC=5V, 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.
