(2) This is the increase in supply current for each input that is at the specified voltage level, rather than VCC or GND. (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 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 S A or B 1.8 6.1 1.8 5.3 ns 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). 4 Submit Documentation Feedback Copyright © 1997–2013, Texas Instruments Incorporated Product Folder Links :SN74CBTLV3257 |
