tc4404/tc4405 ds21418c-page 2 ? 2006 microchip technology inc. 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 dd ), to prevent static damage. in 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 2 kv of electrostatic discharge. functional block diagram input gnd effective input c 12 pf 300 mv v dd pull-up pull-down 2 (3) a (b) 8 (6) 7 (5) 4 1 tc4404 inverting tc4405 noninverting 4.7v
