5 / 28 page SN74CBTLV3257 www.ti.com SCDS040K – DECEMBER 1997 – REVISED APRIL 2015 Electrical Characteristics (continued) over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP(1) MAX UNIT A port 10.5 Cio(OFF) VO = 3 V or 0, OE = VCC pF B port 5.5 II = 64 mA 5 8 VI = 0 VCC = 2.3 V, II = 24 mA 5 8 TYP at VCC = 2.5 V VI = 1.7 V II = 15 mA 27 40 ron (3) Ω II = 64 mA 5 7 VI = 0 VCC = 3 V II = 24 mA 5 7 VI = 2.4 V II = 15 mA 10 15 (3) Measured by the voltage drop between the A and the 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 1) VCC = 2.5 ± 0.2 V VCC = 3.3 V ± 0.3 V PARAMETER FROM (INPUT) TO (OUTPUT) UNIT MIN MAX MIN MAX A or B(1) B or A 0.15 0.25 tpd ns S A or B 1.8 6.1 1.8 5.3 ten S A or B 1.7 6.1 1.7 5.3 ns tdis S A or B 1 4.8 1 4.5 ns ten OE A or B 1.9 5.6 2 5 ns tdis OE A or B 1 5.5 1.6 5.5 ns (1) 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).
