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

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.

Packages: – 7.0 mW/_C From 65_C To 125_C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high−impedance circuit. For proper operation, V
