VI, VO, II, and IO refer to data terminals. (2) All typical values are at VCC = 3.3 V (unless otherwise noted), TA = 25°C. (3) For I/O ports, the parameter IOZ includes the input leakage current. (4) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND. (5) This parameter specifies the dynamic power-supply current associated with the operating frequency of a single control input (see Figure 2). (6) Measured by the voltage drop between the A and B terminals at the indicated current through the switch. ON-state resistance is determined by the lower of the voltages of the two (A or B) terminals. 6.6 Switching Characteristics over recommended operating free-air temperature range (unless otherwise noted) (see Figure 3) VCC = 2.5 V VCC = 3.3 V FROM TO ± 0.2 V ± 0.3 V PARAMETER UNIT (INPUT) (OUTPUT) MIN MAX MIN MAX f OE or fS (1) OE or S A or B 10 20 MHz tpd (2) A or B B or A 0.12 0.2 ns tpd(s) S A 1.5 6.5 1.5 5.5 ns S B 1.5 6.5 1.5 5.5 ten ns OE A or B 1.5 6.5 1.5 5.5 S B 1 6 1 6 tdis ns OE A or B 1 6 1 6 (1) Maximum switching frequency for control inputs (VO > VCC, VI = 5 V, RL ≥ 1 MΩ, CL = 0). (2) The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance, when driven by an ideal voltage source (zero output impedance).
