Change
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
1. The parameters listed in Table 3 are controlled via design or process parameters and are not directly tested. These parameters are char-
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.
PARAMETERS
load and CL
acterized upon initial design release and upon design changes which would affect these characteristics.
PARAMETER
50pF, for CL > 50pF, access times are derated 0.15ns/pF.
