DEVICE INFORMATION
LOW-POWER SHUTDOWN MODE
When both the driver and receiver are disabled (DE low and RE high) the device is in shutdown mode. If the
enable inputs are in this state for less than 60 ns, the device does not enter shutdown mode. This guards against
inadvertently entering shutdown mode during driver/receiver enabling. Only when the enable inputs are held in
this state for 300 ns or more, the device is assured to be in shutdown mode. In this low-power shutdown mode,
most internal circuitry is powered down, and the supply current is typically less than 1 nA. When either the driver
or the receiver is re-enabled, the internal circuitry becomes active.

Figure 13. Low-Power Shutdown Logic Diagram
If only the driver is re-enabled (DE transitions to high) the driver outputs are driven according to the D input after
the enable times given by t
PZH2
and t
PZL2
in the driver switching characteristics. If the D input is open when the
driver is enabled, the driver outputs defaults to A high and B low, in accordance with the driver failsafe feature.
If only the receiver is re-enabled (RE transitions to low) the receiver output is driven according to the state of the
bus inputs (A and B) after the enable times given by t
PZH2
and t
PZL2
in the receiver switching characteristics. If
there is no valid state on the bus the receiver responds as described in the failsafe operation section.
If both the receiver and driver are re-enabled simultaneously, the receiver output is driven according to the state
of the bus inputs (A and B) and the driver output is driven according to the D input. Note that the state of the
active driver affects the inputs to the receiver. Therefore, the receiver outputs are valid as soon as the driver
outputs are valid.
