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.

ORDERING INFORMATION
Ratings are stress ratings only. Functional operation above the Recommended
See
detailed
ordering and shipping information in the package
Operating Conditions is not implied. Extended exposure to stresses above the
dimensions section on page 2 of this data sheet.
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, precautions must be
taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout
should be constrained to the range VSS ≤ (Vin or Vout) ≤ 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.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
3. Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
4. The formulas given are for the typical characteristics only at 25_C.
5. 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.
