6 Functional Description
6.1 Supply Voltages / POR
Upon power-up of the supply voltage all data latches
and the timers are reset and the output drivers are disa-
bled (OUTx = inactive HIGH). The internal Power-On-Re-
set is OR'd with the external RESETB input. An analogue
low pass fi lter is added to the RESETB input in order to
prevent short spikes on the signal line from triggering

After both, internal Power-On-Reset and external RE-
SETB event, have changed to inactive state, the internal
reset condition is extended by a time of T
low the circuit to settle properly before normal func-
tion is enabled (See timing diagrams)
