Description

The CD74HC4518 is a dual BCD up-counter. The ’HC4520

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

NOTE: When ordering, use the entire part number. The sufﬁx 96

denotes tape and reel. The sufﬁx T denotes a small-quantity reel

of 250.
