9.7 34ohm Output Driver DC Electrical Characteristics
A functional representation of the output buffer is shown below. Output driver impedance RON is defined by the value of external reference resistor RZQ
as follows:
RON
RON
The individual Pull-up and Pull-down resistors (RONpu and RONpd) are defined as follows
[ Table 22 ] Output Driver DC Electrical Characteristics, assuming RZQ=240ohms ;
Note :
1. The tolerance limits are specified after calibration with stable voltage and temperature. For the behavior of the tolerance limits if temperature or voltage changes after calibra-
