NOTES:

1. 'X' in part number indicates power rating (SA or LA).
2. VCC = 5V, TA = +25°C for typical, and parameters are not production tested.
3. fMAX = 1/tRC = All inputs cycling at f = 1/tRC (except Output Enable). f = 0 means no address or control lines change. Applies only to inputs at CMOS level standby ISB3.
