MC14521B
24-Stage Frequency Divider
The MC14521B consists of a chain of 24 flipflops 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 flipflop divides the frequency of the previous flipflop
by two, consequently this part will count up to 224 = 16,777,216. The
count advances on the negative going edge of the clock. The outputs of
the last sevenstages are available for added flexibility.
Features
All Stages are Resettable
Reset Disables the RC Oscillator for Low Standby Power Drain
RC and Crystal Oscillator Outputs Are Capable of Driving External
Loads
Test Mode to Reduce Test Time
VDD′ and VSS′ Pins Brought Out on Crystal Oscillator Inverter to
Allow the Connection of External Resistors for LowPower Operation
Supply Voltage Range = 3.0 Vdc to 18 Vdc
Capable of Driving Two LowPower TTL Loads or One LowPower
Schottky TTL Load over the Rated Temperature Range
These Devices are PbFree and are RoHS Compliant
NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AECQ100
Qualified and PPAP Capable

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
highimpedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either VSS or VDD). Unused outputs must be left open.
