Measured peak-to-peak. Tested with Agilent 53132A frequency counter. Due to the low operating frequency, the gate time
must be ≥100ms to ensure an accurate frequency measurement.
Stability is specified for two operating voltage ranges. Stability progressively degrades with supply voltage below 1.5V.
Measured peak-to-peak. Inclusive of initial tolerance at +25°C, and variations over operating temperature, rated power
supply voltage and load.
Core operating current does not include output driver operating current or load current. To derive total operating current (no
load), add core operating current + output driver operating current, where output driver operating current = Cdriver*Vout*Fout.
Measured from the time Vdd reaches 1.5V.

No connection. Will not respond to any input signal.
Connect to ground. All GND pins must be connected
to power supply ground.
Oscillator clock output.
Connect to power supply 1.5V≤Vdd≤3.63V for
operation over -40°C to +85°C temperature range.
Under normal operating conditions, Vdd doesn’t
require external bypass/decoupling capacitor(s).
Internal power supply filtering will reject more than
