6.6 Switching Characteristics

Unless otherwise noted, the typical characteristics in the following table apply to an input voltage of 3.3V, an ambient temperature of 25°C, RQOD= 0 Ω  and a load of COUT= 0.1 µF, ROUT = 100 Ω. See Figure 7-2
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
tON Turn ON Time VIN = 5.0 V 1680 µs
VIN = 3.3 V 1510
VIN = 1.8 V 1320
tR Output Rise Time VIN = 5.0 V 1120 µs
VIN = 3.3 V 915
VIN = 1.8 V 674
SRON Turn ON Slew Rate VIN = 5.0 V 3.61 mV/µs
VIN = 3.3 V 2.91
VIN = 1.8 V 2.15
tOFF Turn OFF Time VIN = 1.8 V to 5.0V ROUT = 100Ω, COUT = 0.1uF 5.22 µs
tFALL Output Fall Time (1)   9.6 µs
ROUT = Open (2) COUT = 10uF, RQOD=0 Ω 0.35 ms
COUT = 10uF, RQOD=100 Ω 3.12 ms
COUT = 100uF; RQOD=0 Ω 4.3 ms
(1) Output may not discharge completely if QOD is not connected to VOUT
(2) See the Timing Application section for information on how ROUT and COUT affect Fall Time.
