High-Speed 4K x 8 Dual-Port Static SRAM Military, Industrial and Commercial Temperature Ranges
4
DC Electrical Characteristics Over the Operating
Temperature and Supply Voltage Range
(1,2,4)
(V
CC
= 5.0V ± 10%)
NOTES:
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.
4. Industrial temperature: for other speeds, packages and powers contact your sales office.
