• Manufacturer: MICROCHIP [Microchip Technology]

TC4404/TC4405
Because neither drain in an output is dependent on the
other, these devices can also be used as open-drain
buffer/drivers where both drains are available in one
device, thus minimizing chip count. Unused open
drains should be returned to the supply rail that their
device sources are connected to (pull-downs to
ground, pull-ups to V
addition, in situations where timing resistors or other
means of limiting crossover currents are used, like
drains may be paralleled for greater current carrying
capacity.

These devices are built to operate in the most demand-
ing electrical environments. They will not latch up under
any conditions within their power and voltage ratings;
they are not subject to damage when up to 5V of noise
spiking of either polarity occurs on their ground pin; and
they can accept, without damage or logic upset, up to
1/2 amp of reverse current (of either polarity) being
forced back into their outputs. All terminals are fully
protected against up to 2kV of electrostatic discharge.
