? semiconductor components industries, llc, 2006 january, 2006 ? rev. 5 1 publication order number: mc14518b/d mc14518b, mc14520b dual up counters the mc14518b dual bcd counter and the mc14520b dual binary counter are constructed with mos p?channel and n?channel enhancement mode devices in a single monolithic structure. each consists of two identical, independent, internally synchronous 4?stage counters. the counter stages are type d flip?flops, with interchangeable clock and enable lines for incrementing on either the positive?going or negative?going transition as required when cascading multiple stages. each counter can be cleared by applying a high level on the reset line. in addition, the mc14518b will count out of all undefined states within two clock periods. these complementary mos up counters find primary use in multi?stage synchronous or ripple counting applications requiring low power dissipation and/or high noise immunity. features ? diode protection on all inputs ? supply voltage range = 3.0 vdc to 18 vdc ? internally synchronous for high internal and external speeds ? logic edge?clocked design ? incremented on positive transition of clock or negative transition on enable ? capable of driving two low?power ttl loads or one low?power schottky ttl load over the rated temperature range ? pb?free packages are available* maximum ratings (voltages referenced to v ss ) (note 1.) symbol parameter value unit v dd dc supply voltage range ?0.5 to +18.0 v v in , v out input or output voltage range (dc or transient) ?0.5 to v dd + 0.5 v i in , i out input or output current (dc or transient) per pin 10 ma p d power dissipation, per package (note 2.) 500 mw t a operating temperature range ?55 to +125 c t stg storage temperature range ?65 to +150 c t l lead temperature (8?second soldering) 260 c maximum ratings are those values beyond which device damage can occur. maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. if these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. maximum ratings are those values beyond which damage to the device may occur. 2. temperature derating: plastic ?p and d/dw? packages: ? 7.0 mw/ c from 65 c to 125 c this device contains protection circuitry to guard against damage due to high static voltages or electric fields. however, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high?impedance circuit. for proper operation, v in and v out should be constrained to the range v ss (v in or v out ) v dd . unused inputs must always be tied to an appropriate logic voltage level (e.g., either v ss or v dd ). unused outputs must be left open. http://onsemi.com xx = 18 or 20 a = assembly location wl, l = wafer lot yy, y = year ww, w = work week g = pb?free indicator marking diagrams 1 16 pdip?16 p suffix case 648 mc145xxbcp awlyywwg soic?16 dw suffix case 751g 1 16 145xxb awlyywwg soeiaj?16 f suffix case 966 1 16 mc145xxb alywg see detailed ordering and shipping information in the package dimensions section on page 7 of this data sheet. ordering information
