When the E/D is set to a logic low, the oscillator stops and the output is in a high impedance state. This helps reduce power consumption as well as facilitating board testing and troubleshooting. Tri-state Functional Description Under normal operation the tri-state is left open or set to a logic high state. When the tri-state is set to a logic low, the oscillator remains active but the output buffer is in a high impedance state. This helps facilitate board testing and troubleshooting. Table 4.

Environnemental Compliance Parameter Mechanical Shock Mechanical Vibration Temperature Cycle Solderability Gross and Fine Leak Resistance to Solvents MSL MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 1 Conditions Method 2022 Method 2007 Method 1010 Method 2003 Method 1014 Method 2015 Handling Precautions Although ESD protection circuitry has been designed into the the VCS3, proper precautions should be taken when handling and mounting. VI employs a Human Body Model and a Charged-Device Model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance = 1.5kohms and capacitance = 100pF is widely used and therefore can be used for comparison purposes.
