Description

RESET A

CD4518BMS Dual BCD Up Counter and CD4520BMS Dual

Binary Up Counter each consist of two identical, internally

synchronous 4-stage counters. The counter stages are

D-type ﬂip-ﬂops having interchangeable CLOCK and

ENABLE lines for incrementing on either the positive-going

or negative-going transition. For single unit operation the

ENABLE input is maintained high and the counter advances

on each positive-going transition of the CLOCK. The

counters are cleared by high levels on their RESET lines.

Q4B

CLOCK B

÷10/÷16

ENABLE B

The counter can be cascaded in the ripple mode by connect-

ing Q4 to the enable input of the subsequent counter while

the CLOCK input of the latter is held low.

RESET B

The CD4518BMS and CD4520BMS are supplied in these

16-lead outline packages:

VSS = 8

VDD = 16
