Table 20.8 X03 Normal N 3.3V Output delays
20.4 Cell DC Characteristics
The characteristics in Table 20.9 below apply to the generic logic input and output cells, of types:
a) Input
- 3.3V:
CLAIO1HD01N, CLAIO1HD03N, CLAIO1NR01N, CLAIP1GD, CLAIP1GU,
CLAIP1NR
CLAIP1NR
b)
Input – 5V:
SCJIO1NR01N, SCJIP1NR,
c)
Output – X01 – Slow:
CLAOP01L1,
d)
Output – X01 – Normal:
CLAIO1HD01N, CLAIO1NR01N, CLAOP01N, SCJIO1NR01N
e)
Output – X03 – Slow:
CLAOP03L1,
f)
Output – X03 – Normal:
CLAIO1HD03N, CLAOP03N
Typical characteristics are with Vdd = +3.3v, Temp = +27
°C and typical silicon process. The min. and max.
characteristics are defined over ALL silicon process conditions, Vdd = +3.0V to +3.6V and Temp = -40
°C to +85°C.
