MC14521B 24-Stage Frequency Divider

MC14521B 24-Stage Frequency Divider The MC14521B consists of a chain of 24 flip−flops with an input 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 w.

Features

• All Stages are Resettable
• Reset Disables the RC Oscillator for Low Standby Power Drain
