* NOTICE: Stresses above those listed under "Absolute
Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only. Functional operation
of the device at or above these conditions is not implied.
Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
ESD CONSIDERATIONS: The model 2420 triaxial
accelerometer is a CMOS device subject to damage by
large electrostatic discharges. Diode protection is
provided on the inputs and outputs but care should be
exercised during handling of the connector or cable wire
ends (without connector). Individuals and tools should be
grounded before coming in contact with the connector
pins or cable wire ends (without connector).
PERFORMANCE - By Model: V_DD=5.0VDC, T_C=25EC.

Note 1: Voltages on the CLK & CNT signal wires may exceed 0.5 volt above or below the supply voltage provided the current is limited to 1 mA.
Note 2: Tighter tolerances available on special order.
Note 3: 100g and greater versions are tested from -65g to +65g.
ALTERNATE OUTPUT VERSION AVAILABLE: A custom version may be ordered which provides the DIR (direction) output
instead of the CNT (count) output. For a description of the DIR signal, see the model 1010 data sheet.
