6.6 Switching Requirements

At VDD(MIN) ≤ VDD ≤ VDD(MAX), CTR = CTS = open and enabled, output RESET pull-up resistor RPU = 10 kΩ, voltage VPU = 5.5 V, output BIST pull-up resistor RPU_BIST = 10 kΩ, voltage VPU_BIST = 5.5 V, and load CLOAD = 10 pF. The operating free-air temperature range TA = – 40°C to 125°C, unless otherwise noted. Typical values are at TA = 25°C and VDD = 12 V and VIT = 6.5 V (VIT refers to VITN or VITP).
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
Common Switching Requirements
tCTR(No Cap) RESET release time delay
(CTR)(1)		 VIT = 800 mV
CCTR = Open
20% Overdrive from Hysteresis		 350 600 µs
tCTS(No Cap) Sense detect time delay 
(CTS)(2)		 VIT = 800 mV
CCTS = Open
20% Overdrive from VIT		 85 100 µs
tSD Startup Delay (3) CCTR = Open 1 ms
BIST Switching Requirements
tBIST_en_pd Rising edge of BIST_EN to BIST asserting 2.3 µs
tBIST_en_pd Rising edge of BIST_EN to RESET asserting 2.3 µs
tBIST_recover Rising edge of BIST to SENSE input valid CCTR = Open, BIST = Enabled 350 600 µs
tBIST BIST run time 3.5 ms
tSD+BIST Startup time with BIST run time 4.5 ms
LATCH Switching Requirements
tBIST_EN/LATCH_CLR_Recover Rising edge of BIST to SENSE input valid CCTR = Open, BIST = Disabled 10 µs
(1) CTR Reset detect time delay:
Overvoltage active-low output is measure from VITP - HYS  to VOH
Undervoltage active-low output is measure from VITN + HYS  to VOH
(2) CTS Sense detect time delay:
Overvoltage active-low output is measure from VITP to VOL
Undervoltage active-low output is measure from VITN to VOL
(3) During the power-on sequence, VDD must be at or above VDD (MIN) for at least tSD+BIST + tCTR before the output is in the correct state based on VSENSE. 
tSD time includes the propagation delay (CCTR = Open). Capacitor on CTR will add time to tSD.
