IDT71321SA/LA AND IDT71421SA/LA
HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS
NOTE: 1. At Vcc < 2.0V leakages are undefined.
NOTES:
1. 'X' in part numbers indicates power rating (SA or LA).
2. At f = f
3. f = 0 means no address or control lines change. Applies only to inputs at CMOS level standby.
4. Vcc = 5V, T
5. Port "A" may be either left or right port. Port "B" is opposite from port "A".
