Available division ratios 28, 210, 213, or 216
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 kHz)
Oscillator frequency range ? DC to 100 kHz
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
Operates at 2n frequency divider or single transition timer
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
Wide supply voltage range—3.0V to 15V
High noise immunity—0.45 VDD (typ.)
5V–10V–15V parameter ratings
Symmetrical output characteristics
Maximum input leakage 1 ?A at 15V over full temperature range
High output drive (pin 8) min. one TTL load
