6.5 Electrical Characteristics

Unless otherwise noted, VDD = 5.5 V. Typical values and limits apply for TJ = 25°C. Minimum and maximum limits apply over

the entire junction temperature range for operation, TJ = −40°C to +125°C.

(1)

Limits are ensured. All electrical characteristics having room-temperature limits are tested during production with TJ = 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.

Verified by design.
