Environmental Specification
s Storage Temperature Range: -55 to 125°C
s Vibration: IEC 60068-2-6 Test Fc Procedure B4, 10-60Hz
1.5mm displacement, at 98.1 m/s2, 30 minutes in each
of three mutually perpendicular axes at 1 octave per
minute.
s Shock: IEC 60068-2-27 Test Ea, 980m/s2 acceleration for
6ms duration, 3 shocks in each direction along three
mutually perpendicular axes.
s Solderability: MIL-STD-202, Method 208, Catergory 3.
Resistance to Soldering heat: 260°C / 10 seconds exposure
s RoHS/Soldering: Parts with the suffix ‘LF’ on the part
number are fully compliant with the European Union
directive 2002/95/EC on the restriction of the use of certain
hazardous substances in electrical and electronic
equipment.
Note: The RoHS compiant parts are suitable for
assembly using both Lead-free solders (see Lead-free
Reflow soldering profile) and Tin/Lead solders (see Tin/Lead
Reflow soldering profile).
Tri-state
s Pad 8 open circuit or >0.6Vs : Output Enabled
s Pad 8 < 0.2Vs : Output in tri-state mode
s When in tri-state, the output stage is disabled but the
oscillator
and compensation circuit are still active,
(Current consumption < 1mA)
