DESCRIPTION

The HCF4521B is a monolithic integrated circuit,

available in 16-lead dual-in-line plastic package

and plastic micro packages.

(Plastic Package)

(Micro Package)

ORDER CODES :

The HCF4521B have a chain of 24 flip-flops with

an input circuit that allows three modes of

operation. The input circuit functions as a crystal

or an RC oscillator or as an input buffer for an

external oscillator. Each flip-flop performs a

divide-by-two function giving a total count of 2²⁴

16,777,216. The count advances on the negative

going edge of the clock. Access is available to the

final seven stages giving the device added

flexibility.
