NOTES
1Electrical test are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal
yield loss, yield after packaging is not guaranteed for standard product dice.
2Limits extrapolated from testing of individual bit errors.
3Die offers latch control pad. Edge triggered latches become level triggered when latch control and clock pads are high.
4Die substrate is connected to V
EE.
