Notes
1. All typical values are measured at Tamb = 25 °C.
2. The value of additional quiescent supply current (âICC) for a unit load of 1 is given here. To determine âICC per input,
multiply this value by the unit load coefficient per input pin:
a. pin DS: 0.25
b. pins MR, SH_CP, ST_CP and OE: 1.50.
