AT6000(LV) Series
AC Timing Characteristics – 5V Operation
Delays are based on fixed load. Loads for each type of device are described in the notes. Delays are in nanoseconds.
Worst case: VCC = 4.75V to 5.25V. Temperature = 0°C to 70°C.

Notes:
1. TTL buffer delays are measured from a VIH of 1.5V at the pad to the internal VIH at A. The input buffer load is constant.
2. CMOS buffer delays are measured from a VIH of 1/2 VCC at the apd to the internal VIH at A. The input buffer load is constant.
3. Buffer delay is to a pad voltage of 1.5V with one output switching.
4. Max specifications are the average of mas tPDLH and tPDHL.
5. Parameter based on characterization and simulation; not tested in production
6. Exact power calculation is available in an Atmel application note.
7. Load Definition: 1 = Load of one A or B input; 2 = Load of one L input; 3 = Constant Load; 4 = Tester Load of 50 pF.
