TC4520BP/BF/BFN
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC4520BP,TC4520BF,TC4520BFN
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 two BCD digits or eight binary bits can be achived with one IC. The counters can be reset to "0" (Q0~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".
Note: xxxFN (JEDEC SOP) is not available in Japan. TC4520BP

Absolute Maximum Ratings (Note)
Characteristics DC supply voltage Input voltage Output voltage DC input current Power dissipation Operating temperature range Storage temperature range Symbol VDD VIN VOUT IIN PD Topr Tstg Rating VSS - 0.5~VSS + 20 VSS - 0.5~VDD + 0.5 VSS - 0.5~VDD + 0.5 10 300 (DIP)/180 (SOIC) -40~85 -65~150 Unit V V V mA mW C C
Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
Operating Ranges (VSS = 0 V) (Note)
Characteristics DC supply voltage Input voltage Symbol VDD VIN Test Condition Min 3 0 Typ. Max 18 VDD Unit V V
Note:
The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VDD or VSS.
