Description

The Harris CD74HC4518 is a dual BCD up-counter. The

Harris CD74HC4520 and CD74HCT4520 are dual binary

up-counters. Each device consists of two independent

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 the negative-going transition of CLOCK. The counters are

cleared by high levels on the MASTER RESET lines. The

counter can be cascaded in the ripple mode by connecting

Q3 to the ENABLE input of the subsequent counter while the

CLOCK input of the latter is held low.
