cd4541 Programmable Timer

Cd4541 Programmable Timer in the 45XX category for electronics projects and repairs.

• Increments on positive edge clock transitions
• Built-in low power RC oscillator (±2% accuracy over temperature range and ±10% supply and ±3% over processing @ < 10 k
• Oscillator may be bypassed if external clock is available (apply external clock to pin 3)
• Automatic reset initializes all counters when power turns on
• External master reset totally independent of automatic reset operation
• Q/Q select provides output logic level flexibility
• Reset (auto or master) disables oscillator during resetting to provide no active power dissipation
• Clock conditioning circuit permits operation with very slow clock rise and fall times
• Symmetrical output characteristics
