Description

The CD4518 is a dual BCD up counter that can count in BCD format (i.e., decimal digits 0 through 9) and can be used in various counting and timing applications. It features two independent 4-bit counters that operate in parallel, allowing for simultaneous counting operations. The counters can be configured to provide a carry-out signal, enabling cascading with additional counters to extend counting capability.

Features

  • Dual 4-Bit BCD Counters: Contains two separate 4-bit counters that count in BCD format.
  • Asynchronous Reset: Allows resetting the counters to zero asynchronously.
  • Carry-Out Capability: Provides a carry-out signal for cascading with additional counters.
  • Clear and Load Functions: Includes features for clearing and loading preset values into the counters.
  • Wide Supply Voltage Range: Operates from 3V to 15V, making it compatible with various logic levels.
  • Low Power Consumption: CMOS technology ensures minimal power dissipation.
  • High Noise Immunity: Provides good noise margins, ensuring reliable operation.
  • Standard Pin Configuration: Packaged in a DIP-16 format for easy integration into breadboards and prototyping circuits.

Specifications

  • Logic Family: CMOS
  • Number of Counters: 2 (each 4-bit BCD counter)
  • Counting Mode: Up-counting in BCD format (0 to 9)
  • Operating Voltage Range: 3V to 15V
  • Propagation Delay: Typically around 200ns at VDD = 10V
  • Input Voltage (VIH/VIL): Typically 70%/30% of VDD
  • Output Voltage (VOH/VOL): Close to VDD/VSS
  • Package Type: DIP-16
  • Temperature Range: -40°C to +85°C (standard version)
