Appendix A
Electrical Characteristics and Timing Specifications
A.1 Introduction
This section contains electrical and timing specifications.
A.2 Parameter Classification
The electrical parameters shown in this supplement are guaranteed by various methods. To give the
customer a better understanding, the following classification is used and the parameters are tagged
accordingly in the tables where appropriate:
Table A-1. Parameter Classifications
P Those parameters are guaranteed during production testing on each individual device.
C
Those parameters are achieved by the design characterization by measuring a
statistically relevant sample size across process variations.
Those parameters are achieved by design characterization on a small sample size
T from typical devices under typical conditions unless otherwise noted. All values
shown in the typical column are within this category.
D Those parameters are derived mainly from simulations.
NOTE
The classification is shown in the column labeled “C” in the parameter
tables where appropriate.
A.3 Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not
guaranteed. Stress beyond the limits specified in Table A-2 may affect device reliability or cause
permanent damage to the device. For functional operating conditions, refer to the remaining tables in this
section.
This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (for instance, either V_SS or V_DD).
