4029 IC Up-Down Counter

Description

Features:-

High-Voltage Type (20V Rating)

Medium Speed Operation: 8MHz (Typ.) at CL = 50pF and VDD – VSS = 10V • Multi-Package Parallel Clocking for Synchronous High-Speed Output Response or Ripple Clocking for Slow Clock Input Rise and Fall Times

“Preset Enable” and Individual “Jam” Inputs Provided • Binary or Decade Up/Down Counting

BCD Outputs in Decade Mode

100% Tested for Maximum Quiescent Current at 20V

5V, 10V and 15V Parametric Ratings

Standardized Symmetrical Output Characteristics

Maximum Input Current of 1A at 18V Over Full Package-Temperature Range; 100nA at 18V and +25oC

Noise Margin (Over Full Package Temperature Range): – 1V at VDD = 5V – 2V at VDD = 10V – 2.5V at VDD = 15V
