Tranzistorove pole pre kladnu vetvu

[Miroslav Sinko]

Dobry den,

vedeli by ste mi poradit IO - tranzistorove pole aspon styroch PNP
alebo P-MOS tranzistorov, schopne dodat prud 50mA na jeden budic, ale s
ubytkom napatia max 0.5V pri tomto prude? 

Nieco ako TD62783, ale tento ma saturacne napatie 1.8 - 2V, to je vela.
Pole zlozene z BC640 by bolo idealne.

Pripadne nejaky budic zbernice, ale so samostatnymi OE pre kazdy bit.
Nieco ako 74HC125, ale ten tiez nevyhovuje ubytkom napatia.

Vdaka,
miro
