4 / 15 page 6.42 IDT70121/IDT70125 High-Speed 2K x 9 Dual-Port Static RAM with Busy & Interrupt Industrial and Commercial Temperature Ranges 4 APRIL 05, 2006 DC Electrical Characteristics Over the Operating Temperature and Supply Voltage Range(1,4) (VCC = 5V ± 10%) NOTES: 1. 'X' in part numbers indicates power rating (S or L). 2. 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. 3. f = 0 means no address or control lines change. Applies only to inputs at CMOS level standby. 4. Vcc=5V, TA=+25°C for Typ, and is not production tested. 5. Port "A" may be either left or right port. Port "B" is opposite from port "A". 70121X25 70125X25 Com'l Only 70121X35 70125X35 Com'l & Ind Symbol Parameter Test Condition Version Typ. Max. Typ. Max.
