Operating Characteristics Notes:
1. Not including any current drawn from the device pins by external circuitry.
2. ENABLE pin.
3. DETECT1 and DETECT2 pins.
4. Small signal impedance over the frequency range 100Hz to 2000Hz and at 5.0V
5. The input level is not critical as the detector uses a stochastic algorithm.
6. Timing for an external input to the XTAL/CLOCK pin.
