On-state resistance is determined by the lowest voltage of the two (A or B) terminals. switching characteristics over recommended operating free-air temperature range, CL = 50 pF (unless otherwise noted) (see Figure 1) PARAMETER FROM TO SN54CBT3383 SN74CBT3383 UNIT PARAMETER (INPUT) (OUTPUT) MIN MAX MIN MAX UNIT tpd¶ A or B B or A 1.5 0.25 ns tpd BX A or B 1 10.2 1 9.2 ns ten BE A or B 1 10.8 1 8.6 ns tdis BE A or B 1 8.2 1 7.5 ns ¶ 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). |
