NOTES:
1. All typical values are at VCC = 5V, Tamb = +25°C.
2. For 3-State output; output enable times are tested with CL = 30pF to the 1.5V level, and S1 is open for high-impedance to High tests and
closed for high-impedance to Low tests. Output disable times are tested with CL = 5pF. High-to-High impedance tests are made to an output
voltage of VT = (VOH – 0.5V) with S1 open, and Low-to-High impedance tests are made to the VT = (VOL + 0.5V) level with S1 closed.
3. All propagation delays and setup times are measured and specified under worst case conditions.
