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 µA at 15V over full temperature
range
■ High output drive (pin 8) min. one TTL load
