6.5 Electrical Characteristics
Unless otherwise noted, V_DD = 5.5 V. Typical values and limits apply for T_J = 25°C. Minimum and maximum limits apply over
the entire junction temperature range for operation, T_J = −40°C to +125°C.⁽¹⁾

(1) Limits are ensured. All electrical characteristics having room-temperature limits are tested during production with T_J = 25°C. All hot and
cold limits are ensured by correlating the electrical characteristics to process and temperature variations and applying statistical process
control.
(2) Each LED pin must not exceed 25 mA and each octal (LED0–LED7; LED8–LED15) must not exceed 100 mA. The package must not
exceed a total of 200 mA.
(3) Verified by design.
