NOTES:
2721 tbl 06b
1. 'X' in part number indicates power rating (SA or LA).
2. V CC = 5V, T A = +25°C for typical, and parameters are not production tested.
3. f MAX = 1/t RC = All inputs cycling at f = 1/t RC (except Output Enable). f = 0 means no address or control lines change. Applies only to inputs at CMOS level standby I SB3.
