6.7 Electrical Characteristics: SN54LVCH245A

over recommended operating free-air temperature range (unless otherwise noted)
PARAMETER TEST CONDITIONS VCC MIN TYP(1) MAX UNIT
VOH High-level
output voltage		 IOH = –100 µA 2.7 V to 3.6 V VCC – 0.2 V
IOH = –12 mA 2.7 V 2.2
3 V 2.4
IOH = –24 mA 3 V 2.2
VOL Low-level
output voltage		 IOL = 100 µA 2.7 V to 3.6 V 0.2 V
IOL = 12 mA 2.7 V 0.4
IOL = 24 mA 3 V 0.55
II Input current Control inputs:
VI = 0 to 5.5 V		 3.6 V ±5 µA
II(hold) Input hold current VI = 0.8 V 3 V 75 µA
VI = 2 V –75
VI = 0 to 3.6 V(2) 3.6 V ±500
IOZ(3) High-impedance state output current VO = 0 V or (VCC to 5.5 V) 2.3 V to 3.6 V ±15 µA
ICC Supply current VI = VCC or GND IO = 0 3.6 V 10 µA
3.6 V ≤ VI ≤ 5.5 V(4) IO = 0 3.6 V 10
ΔICC Supply-current change One input at VCC  – 0.6 V, other inputs at VCC or GND 2.7 V to 3.6 V 500 µA
Ci Input capacitance Control inputs:
VI = VCC or GND		 3.3 V 4 12 pF
Cio Input and output
capacitance		 A or B port:
VO = VCC or GND		 3.3 V 5.5 12 pF
(1) All typical values are VCC = 3.3 V, TA = 25°C.
(2) The bus-hold maximum dynamic current requirement to switch the input from one state to another state.
(3) For the total leakage current in an I/O port, see the II(hold) specification for the input voltage condition 0 V < VI < VCC, and the IOZ specification for the input voltage conditions VI = 0 V or VI = VCC to 5.5 V. A bus-hold current with an input voltage greater than VCC is negligible.
(4) This only applies when in a disabled state.
