Description

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 MC14521B advances on the negative going edge of the clock. The outputs of the last sevenstages are available for added flexibility.
• 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
• VDD4 and VSS4 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.
