Description

• Positive or Negative Edge Triggering

• Synchronous Internal Carry Propagation

• Fanout (Over Temperature Range)

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
