Table 2. Wake–Up Truth Table
ENABLE
The
SP211EH
and
SP213EH
all feature an
enable input, which allows the receiver outputs
to be either tri–stated or enabled. This can be
especially useful when the receiver is tied di-
rectly to a microprocessor data bus. For the
SP211EH
, enable is active low; that is, 0V
applied to the ENABLE pin will enable the
receiver outputs. For the
SP213EH
, enable is
active high; that is, +5V applied to the ENABLE
pin will enable the receiver outputs.
