Electrical Characteristics
The ST7FLCD1 device contains circuitry to protect the inputs against damage due to high static
voltage or electric field. Nevertheless it is advised to take normal precautions and to avoid applying
to this high impedance voltage circuit any voltage higher than the maximum rated voltages. It is
recommended for proper operation that VIN and VOUT be constrained to the range:
VSS ≤(VIN or VOUT) ≤VDD
To enhance reliability of operation, it is recommended to connect unused inputs to an appropriate
logic voltage level such as VSS or VDD. All the voltages in the following table, are referenced to VSS.

Power Considerations
The average chip-junction temperature, TJ, in degrees Celsius, may be calculated using the
following equation:
TJ = TA + (PD x θJA) (1)
Where:
TA is the Ambient Temperature in ° C,
θJA is the Package Junction-to-Ambient Thermal Resistance, in ° C/W,
PD is the sum of PINT and PI/O,
PINT is the product of IDD and VDD, expressed in Watts. This is the Chip Internal Power
PI/O represents the Power Dissipation on Input and Output Pins; User Determined.
