NOTES:

1. All voltages referenced to device GND.

2. AC measurements assume transition time

≤ 5ns; input levels = 0.0V to 3.0V; timing reference levels = 1.5V; output load = 1TTL equivalent

load and CL

≥ 50pF, for CL > 50pF, access times are derated 0.15ns/pF.

NOTES:

1. The parameters listed in Table 3 are controlled via design or process parameters and are not directly tested. These parameters are char-

acterized upon initial design release and upon design changes which would affect these characteristics.

2. Applies to DIP device types only. For design purposes CIN = 6pF typical and CI/O = 7pF typical.

3. Applies to LCC device types only. For design purposes CIN = 4pF typical and CI/O = 5pF typical.
