ADG1414 Data Sheet TIMING CHARACTERISTICS
All input signals are specified with tR = tF = 1 ns/V (10% to 90% of VDD) and timed from a voltage level of (VIL + VIH)/2 (see Figure 2). VDD = 4.5 V to 16.5 V; VSS = −16.5 V to 0 V; VL = 2.7 V to 5.5 V or VDD (whichever is less); GND = 0 V; all specifications TMIN to TMAX, unless otherwise noted. Guaranteed by design and characterization, not production tested.
