1 All voltages are measured with respect to GND, unless otherwise specified. Typical values are at TA = 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 VIL = 0.8 V for a

falling edge and at VIH = 2.0 V for a rising edge.

2 Guaranteed by design, not production tested.
