GTLP8T306
DC Electrical Characteristics (Continued)
Note 4: All typical values are VCC = 3.3V and TA= 25°C.
Note 5: For conditions shown as Min, use the appropriate value specified under recommended operating conditions.
Note 6: This is the increase in supply current for each input that is at the specified LVTTL voltage level rather than VCC or GND.
AC Electrical Characteristics
Over recommended range of supply voltage and operating free air-temperature, VREF = 1.0V (unless otherwise noted).
CL = 30 pF for B Port and CL = 50 pF for A Port.
Note 7: All typical values are at VCC = 3.3V and TA = 25°C.
