Quadruple Dfferential Line Receivers With 3 State Outputs
Manufacturer
Renesas Electronics Corporation.
Datasheet
HD293486
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.
