MC14518B Dual Up Counters
The MC14518B dual BCD counter and the MC14520B dual binary counter are constructed with MOS Pchannel and Nchannel enhancement mode devices in a single monolithic structure. Each consists of two identical, independent, internally synchronous 4stage c o u n t e r s . The counter stages are type D flipflops, with interchangeable Clock and Enable lines for incrementing on either the positivegoing or negativegoing 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 multistage synchronous or ripple counting applications requiring low power dissipation and/or high noise immunity.

2. Maximum Ratings are those values beyond which damage to the device may occur. 3. 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 highimpedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS v (Vin or Vout) v VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.

The formulas given are for the typical characteristics only at 25_C. 6. To calculate total supply current at loads other than 50 pF: IT(CL) = IT(50 pF) + (CL 50) Vfk where: IT is in µA (per package), CL in pF, V = (VDD VSS) in volts, f in kHz is input frequency, and k = 0.002.
