NOTES:

1. Measurements with 0.4 ≤ VIN ≤ VCC.

2. OE ≥ VIH, 0.4 ≤ VOUT ≤ VCC.

3 & 4. Tested at f = 20MHz with outputs unloaded.

(3) Typical Icc1 = 60 + (fCLK*0.57/MHz) + (fCLK*CL*0.02/MHz-pF) mA

(4 ) Typical Icc1 = 80 + (fCLK + 0.73/MHz) + (fCLK*CL*0.02/MHz-pF) mA

fCLK = 1/tCLK, CL = external capacitive load (30 pF typical)
