(2) This information was not available at the time of publication. (3) This is the bus-hold maximum dynamic current required to switch the input from one state to another. (4) For the total leakage current in an I/O port, consult the II(hold) specification for the input voltage condition, 0 V < VI < VCC, and the IOZ specification for the input voltage conditions, VI = 0 V or VI = VCC to 5.5 V. The bus-hold current, at input voltage greater than VCC, is negligible. (5) This applies in the disabled state only. over recommended operating free-air temperature range (unless otherwise noted) (see Figure 1) VCC = 1.8 V VCC = 2.5 V VCC = 3.3 V VCC = 2.7 V ± 0.15 V ± 0.2 V ± 0.3 V UNIT MIN MAX MIN MAX MIN MAX MIN MAX tw Pulse duration, LE or CE low (1) (1) 3.3 3.3 ns tsu Setup time, data before LE or CE ↓ (1) (1) 1.1 1.1 ns th Hold time, data after LE or CE ↓ (1) (1) 1.9 1.9 ns (1) This information was not available at the time of publication. 6 |
