1 DVND IN DVI, IN. D50 QUD PIION HIGH PD MIOPOW TIM GN DIPTION Th D50 timr is a high prformanc QUD monolithic timing circuit uilt with advancd silicon gat MO tchnology. It offrs th nfits of high input impdanc, thry allowing smallr timing capacitors and longr timing cycl; high spd with typical cycl tim of 500ns; low powr dissipation for attry opratd nvironmnt; and rducd supply currnt spiks allowing smallr and lowr cost dcoupling capacitors. ach of th four timrs can indpndntly opratd in ithr th monostal, astal, or 50% duty cycl mod. ach timr is capal of producing accurat tim dlays and oscillations in oth monostal and astal opration. It oprats in th on-shot (monostal) mod or 50% duty cycl fr running oscillation mod with a singl rsistor and on capacitor. Th inputs and outputs ar fully compatil with MO, NMO or TT logic. Thr ar thr matchd intrnal rsistors (approximatly 0KΩ ach) that st th thrshold and triggr lvls at two-thirds and on-third rspctivly of. Ths lvls can adjustd y using th control trminal. Whn th triggr input is low th triggr lvl, th output is in th high stat and sourcing m. Whn th thrshold input is aov th thrshold lvl at th sam tim th triggr input is aov th triggr lvl, th intrnal flip-flop is rst, th output gos to th low stat and sinks up to 0m. Th rst input ovrrids all othr inputs and whn it is activ (rst voltag lss than V), th output is in th low stat. ll four timrs shar th sam control and rst pins so that timing functions ar synchronizd.
