? semiconductor components industries, llc, 2014 july, 2014 ? rev. 8 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 ? nlv prefix for automotive and other applications requiring unique site and control change requirements; aec?q100 qualified and ppap capable ? this device is pb?free and is rohs compliant 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 stresses exceeding maximum ratings may damage the device. maximum ratings are stress ratings only. functional operation above the recommended operating conditions is not implied. extended exposure to stresses above the recommended operating conditions may affect device reliability. 1. maximum ratings are those values beyond which damage to the device may occur. 2. temperature derating: ?d/dw? package: ?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, precautio ns 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 diagram soic?16 wb dw suffix case 751g 1 16 145xxb awlyywwg see detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet. ordering information pin assignment 13 14 15 16 9 10 11 12 5 4 3 2 1 8 7 6 q1 b q2 b q3 b r b v dd c b e b q0 b q1 a q0 a e a c a v ss r a q3 a q2 a
