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
counters. 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.

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
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.
