IDT70V25S/L

High-Speed 8K x 16 Dual-Port Static RAM

Industrial and Commercial Temperature Ranges

6

DC Electrical Characteristics Over the Operating

Temperature and Supply Voltage Range(1) (VCC = 3.3V ± 0.3V)

NOTES:

1. 'X' in part number indicates power rating (S or L)

2. VCC = 3.3V, TA = +25°C, and are not production tested. Icc dc = 115mA (typ.)

3. At f = fMAX

, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/tRC, and using “AC Test Conditions” of input levels of GND

to 3V.

4. f = 0 means no address or control lines change.

5.

Port "A" may be either left or right port. Port "B" is the opposite from port "A".
