Electrical Characteristics
Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature range of -40°C to
+125°C. Unless otherwise specified, the following conditions apply: VIN = 12V, VCC = 8V, VCCDIS = 0V, EN2 = 5V, RT =
25k
Ω, no load on LO and HO. Electrical characteristics are per channel where applicable. See
(1), (2), and (3).

(1)
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which
the device is intended to be functional. For specifications and test conditions see the Electrical Characteristics Table.
(2)
All limits are specified. All electrical characteristics having room temperature limits are tested during production at TA = 25°C. All hot and
cold limits are specified by correlating the electrical characteristics to process and temperature variations and applying statistical process
control.
(3)
Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation
using Statistical Quality Control (SQC) methods. Limits are used to calculate Texas Instrument's Average Outgoing Quality Level
(AOQL).
