5 / 19 page 6.42 IDT70261S/L High-Speed 16K x 16 Dual-Port Static RAM with Interrupt Industrial and Commercial Temperature Ranges 5 DC Electrical Characteristics Over the Operating Temperature and Supply Voltage Range(1) (VCC = 5.0V ± 10%) NOTES: 1. 'X' in part numbers indicates power rating (S or L). 2. VCC = 5V, TA = +25°C, and are not production tested. ICCDC = 120mA (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". 70261X15 Com'l Only 70261X20 Com'l & Ind 70261X25 Com'l & Ind Symbol Parameter Test Condition Version Typ. (2) Max.
