SN74ACT244PWR 8-ch, 4.5-V mpaka 5.5-V mabafa okhala ndi zolowetsa za CMOS zogwirizana ndi TTL ndi zotuluka m'mayiko atatu

Kufotokozera mwachidule:

Buffer iyi ya SN74ACT244PWR ndi woyendetsa mzere amagwiritsidwa ntchito kukulitsa chizindikiro cha analogi kapena digito poyendetsa zolowera pamzere wotumizira.Ndi kutulutsa kwa 3-state, uku ndikuwongolera mphamvu kwabwino kwambiri.Dalaivala wa mzerewu ali ndi kutentha kochepa kwambiri kwa -40 °C ndi kupitirira 85 °C.Izi zitha kutumizidwa mu tepi ndi ma reel kuti zitheke kukweza mwachangu komanso kutumiza bwino.Chida ichi chosagwiritsa ntchito inverting chimakhala ndi mphamvu yogwiritsira ntchito voteji ya 5 V. Mphamvu yake yocheperapo yogwiritsira ntchito 4.5 V, pamene pazipita zake ndi 5.5 V. Ili ndi njira 8 pa chip.
