† All typical values are at VCC = 5 V, TA = 25°C.

‡ The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, IOS.

NOTE 1: With 4.5 V applied to the serial input and all other inputs, except the CLK, grounded, ICC is measured after a clock transition from

0 to 4.5 V.
