CD4510 - CMOS Presettable BCD Up/Down Counter

Details

Description

The CD4510 is a CMOS presettable BCD (Binary Coded Decimal) up/down counter IC from Texas Instruments. This versatile counter can count up or down in BCD format (0-9) and can be preset to any BCD value. It features synchronous operation and is ideal for applications requiring decimal counting, frequency division, and digital control systems.

Applications

Common use cases and applications for this component:

  • Digital frequency counters
  • Event counters and timers
  • BCD data processing systems
  • Digital clocks and time displays
  • Process control counters
  • Cascaded multi-digit counters
  • Programmable dividers
  • Industrial control systems

Circuit Examples

Basic BCD Counter

VDD (Pin 16) ---- +5V to +18V
VSS (Pin 8)  ---- Ground
CLK (Pin 12) ---- Clock input signal
U/D (Pin 11) ---- Up/Down control (high=up, low=down)
RST (Pin 15) ---- Reset control (tie low if not used)
PE (Pin 10)  ---- Preset enable (tie low if not used)
Q0-Q3 (Pins 1-4) -- BCD output to display decoder

Cascaded Multi-Digit Counter

Counter 1 CO (Pin 13) -> Counter 2 CLK (Pin 12)
Counter 1 BO (Pin 14) -> Counter 2 U/D (Pin 11)
Connect all reset and control signals in parallel

Technical Notes

Important technical considerations and features:

  • Counts in BCD format (0000 to 1001, representing 0-9)
  • Preset inputs (P0-P3) allow loading any BCD value when PE is high
  • Up/Down control determines counting direction
  • Carry Out (CO) goes high when counting up from 9 to 0
  • Borrow Out (BO) goes high when counting down from 0 to 9
  • Reset input clears counter to 0000 when high
  • Synchronous operation ensures clean counting transitions
  • Can be cascaded for multi-digit BCD counting
  • Proper power supply decoupling recommended near VDD/VSS pins

Notes

The CD4510 is an essential IC for BCD counting applications and digital systems requiring decimal counting. Its presettable feature makes it very flexible for applications where you need to start counting from a specific value. The up/down capability and cascading outputs make it ideal for building multi-digit counters and complex counting systems. This IC is commonly used in digital clocks, frequency counters, and industrial control applications.
