Notes:

Output stage is low-side open-drain; ext. pull-up resistor required as no pull-up
structure on chip
No hysteresis implemented

To govern the data transfer at data port D3, …,D0 strobe pin DSTBn is equipped with a low-
side open-drain output switch plus a passive high-side current source with a nom. 10 μA pull-
up current capability.
However a second function is assigned to the DSTBn pin which requires it to be input as well:
if a low-pulse is imposed on DSTBn by external means with a pulse width of at least 50 to 100
ms, the slave device will be put in RESET condition, as described in section “Reset”.
The dc-and timing parameters of strobe pin DSTBn are specified as follows:

Notes:
1
DSTBn is equipped with an on-chip pull-up current source, which ensures
a sufficiently fast LH-edge upon output switch-off in open-pin condition,
to prevent erroneous RESET triggering.
If DSTBn has an external load connected to it,
an additional external pull-up resistor may be needed
to prevent erroneous RESET triggering upon output switch-off
No hysteresis implemented
