TC4520BP

TC4520BP/BF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC4520BP, TC4520BF TC4520B Dual Binary Up Counter TC4520B is up counters of 4 bit binary. Since both of TC4520B contain two independent circuits of counters with the same functions in one package, counting or frequency division of eight binary bits can be achived with one IC. The counters can be reset to “0” (Q0 to Q3 = “L”) by giving “H” level signal to RESET input regardless of other inputs. The counting condition is changed by the rising edge of CLOCK input if ENABLE = “H” or by the falling edge of ENABLE if CLOCK = “L”.
