MC14521B

24−Stage Frequency Divider

circuit that allows three modes of operation. The input will function as a

crystal oscillator, an RC oscillator, or as an input buffer for an external

oscillator. Each flip−flop divides the frequency of the previous flip−flop

by two, consequently this part will count up to 2

count advances on the negative going edge of the clock. The outputs of

the last seven−stages are available for added flexibility.

Features

•

Stresses exceeding Maximum Ratings may damage the device. Maximum

Ratings are stress ratings only. Functional operation above the Recommended

Operating Conditions is not implied. Extended exposure to stresses above the

Recommended Operating Conditions may affect device reliability.
