Product data sheet
testing but it was not damaged. Whenever there is current flowing in any of these diodes it
is possible that there can be faulty operation of any IC. For that reason we put a
specification on the negative voltage that is allowed to be applied. It is selected so that, at
the highest allowed junction temperature, there will be a big safety factor that guarantees
the diode will not conduct and then we do not need to make any 100 % production tests to
guarantee the published specification.
For the PCA9600, in specific applications, there will always be transient overshoot and
ringing on the wiring that can cause these diodes to conduct. Therefore we designed the
IC to withstand those transients and as a part of the qualification procedure we made
tests, using DC currents to more than twice the normal bus sink currents, to be sure that
the IC was not affected by those currents. For example, the TX/TY and RX/RY pins were
tested to at least 80 mA which, from
functioning of the PCA9600 is not affected even by those large currents. The Absolute
Maximum (DC) ratings are not intended to apply to transients but to steady state
conditions. This explains why you will never see any problems in practice even if, during
transients, more than 0.3 V is applied to the bus interface pins of PCA9600.

DC specification was selected. The current at 25 C is near zero at 0.55 V. The PCA9600
is allowed to operate with +125 C junction and that would cause this diode voltage to
decrease by 100
publish 0.3 V just to have some extra margin.
Remark: You should not be concerned about the transients generated on the wiring by a
PCA9600 in normal applications and that is input to the TX/RX or TY/RY pins of another
PCA9600. Because not all ICs that may be driven by PCA9600 are designed to tolerate
negative transients, in
they can be managed if required.
