(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but does not ensure specific performance limits. For ensured specifications and conditions,
see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.

Electrical Characteristics
Specifications with standard typeface are for T
J
= 25°C, and those in bold face type apply over the full Operating Temperature
Range (T
J
= -40°C to +125°C). Minimum and Maximum limits are specified through test, design or statistical correlation.
Typical values represent the most likely parametric norm at T
J
= 25°C and are provided for reference purposes only. V
CC
=
3.3V, and limits apply to all timing options, unless otherwise specified.

(1) Limits are 100% production tested at 25°. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods. The limits are used to calculate TI's Average Outgoing Quality Level (AOQL).
(2) Typical numbers are at 25°C and represent the most likely parametric norm.
