INTERFACE TIMING CHARACTERISTICS  
Guaranteed by design, not subject to production test. See Figure 3 for location of measured values. All input control voltages are  
specified with tR = tF = ꢀ.5 ns (10% to 90% of 3 V), and timed from a voltage level of 1.5 V. Switching characteristics are measured  
using both VDD = 3 V and 5 V.

1 During power-up, all outputs preset to midscale before restoring to the final EEMEM contents. RDAC0 has the shortest, whereas RDAC3 has the longest EEMEM data  
restoring time.  
2 Retention lifetime equivalent at junction temperature TJ = 55°C per JEDEC Std. 22, Method A117. Retention lifetime based on an activation energy of 0.6 eV derates  
with junction temperature.  
3 When the part is not in operation, the SDA and SCL pins should be pulled to high. When these pins are pulled to low, the I2C interface at these pins conducts current of  
about 0.8 mA at VDD = 5.5 V and 0.2 mA at VDD = 2.7 V.
