MC14521BCP 24-Stage Frequency Divider DIP-16 IC

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 224 = 16,777,216. The 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 • 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 Low−Power Operation • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low−Power TTL Loads or One Low−Power Schottky TTL Load over the Rated Temperature Range Specifications: Product Attribute | Symbol | Attribute Value DC Supply Voltage Range | VDD | −0.5 to +18.0 V Input or Output Voltage Range (DC or Transient) | Vin, Vout | −0.5 to VDD +0.5 Input or Output Current (DC or Transient) per Pin | Iin, Iout | ±10mA Power Dissipation | PD | 500mW Ambient Temperature Range | TA | −55 to +125 °C Package/Case: PDIP-16 Mounting Style: Through Hole Product Category: Multipliers / Dividers MC14521BCP Datasheet
