AC Timing Characteristics – 5V Operation

Notes:

1. TTL buffer delays are measured from a V

IH

of 1.5V at the pad to the internal V

IH

at A. The input buffer load is constant.

2. CMOS buffer delays are measured from a V

IH

of 1/2 V

CC

at the apd to the internal V

IH

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 t

PDLH

and t

PDHL

.

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.

Delays are based on fixed load. Loads for each type of device are described in the notes. Delays are in nanoseconds.
