#Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
**The formulas given are for the typical characteristics only at 25 C.
When using the on chip oscillator the total supply current (in
μ
Adc) becomes: IT = ID + 2 Ctc VDD f x 10–3 where ID is in
μ
A, Ctc is in pF,
VDD in Volts DC, and f in kHz. (see Fig. 3) Dissipation during power–on with automatic reset enabled is typically 50
μ
A @ VDD = 10 Vdc.
This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However,
precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance
circuit. For proper operation, Vin and Vout should be constrained to the range VSS
≤
(Vin or Vout)
≤
VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must
be left open.
