6.6 Switching Characteristics

At VDD(MIN) ≤ VDD ≤ VDD(MAX), CTR = CTS = open, output OUT A and OUT B pull-up resistor with RPU = 10kΩ and VPU = 5.5V. The operating free-air temperature range TA = -40°C to 125°C, unless otherwise noted. Typical values are at TA = 25°C and VDD = 16V. VIT refers to VITN or VITP. AOUT CLoad = 100nF and AOUT VOUT = 2.5V.

tSD Startup Delay (3) CCTR = Open 1 ms
tBIST Test time for BIST 2.5 ms
(1) CTR Release 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:
Active-low output is measure from VIT to VOL (or VPullup)
(3) During the power-on sequence, VDD must be at or above VDD (MIN) for at least tSD before the output is in the correct state.
(4) This parameter is established by design and/or characterization and is not tested in production.
(5) CCTS = Open assumes there is less than 20pF of parasitic capacitance on the pin.
