  • Tristate Function (Pad 1): Output (Pad 3) is active if Pad 1 is not connected or a voltage to Pad 1 is ‘HIGH’. Output is high impedance when ‘LOW’ or GROUND is applied to Pad 1.

* Frequency stability is inclusive of calibration tolerance at 25°C, frequency change due to shock & vibration, ±10 supply voltage variation and stability over temperature range.

Note: Parameters are measured at ambient temperature of 25°C, supply voltage as stated and a load of 15pF.
