Electrical Characteristics (Continued)
Unless otherwise noted, V
DD = 5.5V. Typical values and limits appearing in normal type apply for TJ = 25˚C. Limits appearing
in boldface type apply over the entire junction temperature range for operation, T
J = −40˚C to +125˚C. (Note 5)

Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical
Characteristics tables.
Note 2: All voltages are with respect to the potential at the GND pin.
Note 3: The part cannot dissipate more than 400mW.
Note 4: The human-body model is 100 pF discharged through 1.5 k
Ω. The machine model is 0Ω in series with 100 pF.
Note 5: Limits are guaranteed. All electrical characteristics having room-temperature limits are tested during production with TJ = 25˚C. All hot and cold limits are
guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
Note 6: Each LED pin should not exceed 25 mA and each octal (LED0–LED7; LED8–LED15) should not exceed 100 mA. The package should not exceed a total
of 200 mA.
Note 7: Guaranteed by design.
