V
All voltages are measured with respect to GND, unless otherwise specified.
Typical values are at %A = 25°C and represent the most likely parametric norm.
Logic inputs accept input high voltages up to 5 V even when the device is operating at supply voltages below 5 V.
Timing specifications are tested at logic levels of V
