Quadruple Dfferential Line Receivers With 3 State Outputs
The HD293486 features quadruple Differential
line receivers designed to meet the specs of EIA
RS–422A and RS–423A. This device operates
from a single 5 V power supply. When the
enable input is low the associated outputs are in a
high impedance state.

Notes: 1. The above data were taken by the ∆VEB method mounting on a glass epoxy board
(40 × 40 × 1.6 mm) of 10 % wiring density.
2. All voltage values except for differential input voltage are with respect to ground terminal.
3. Differential input voltage is measured at the noninverting input with respect to the
corresponding inverting input.
4. The absolute maximum ratings are values which must not individually be exceeded, and
furthemore, no two of which may be realized at the same time.
