the mc10h166 is a 5bit magnitude comparator and is a functional/ pinout duplication of the standard mecl 10k part with 100% improvement in propagation delay and no increase in powersupply current. the mc10h166 is a highspeed expandable 5bit comparator for comparing the magnitude of two binary words. two outputs are provided: ab. the a = b function can be obtained by wireoring these outputs (a low level indicates a = b) or by wirenoring the outputs (a high level indicates a = b). a high level on the enable function forces both outputs low. ? propagation delay, datatooutput, 2.0 ns typical ? power dissipation 440 mw typical ? improved noise margin 150 mv (over operating voltage and temperature range) ? voltage compensated ? mecl 10kcompatible dip pin assignment v cc1 a>b a b word a < word b h l l l xxl l h l l h l l word a = word b word a > word b pin assignment is for dualinline package. for plcc pin assignment, see the pin conversion tables on page 18 of the on semiconductor mecl data book (dl122/d). http://onsemi.com device package shipping ordering information mc10h166l cdip16 25 units/rail mc10h166p pdip16 25 units/rail mc10h166fn plcc20 46 units/rail marking diagrams 1 16 a = assembly location wl = wafer lot yy = year ww = work week cdip16 l suffix case 620 mc10h166l awlyyww pdip16 p suffix case 648 plcc20 fn suffix case 775 10h166 awlyyww 1 1 16 mc10h166p awlyyww
