4 / 17 page 6.42 IDT71321SA/LA and IDT71421SA/LA High Speed 2K x 8 Dual-Port Static RAM with Interrupts Industrial and Commercial Temperature Ranges 4 DC Electrical Characteristics Over the Operating Temperature and Supply Voltage Range(1,4) (VCC = 5.0V ± 10%) NOTES: 1. 'X' in part numbers indicates power rating (SA or LA). 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. Vcc DC = 100mA (Typ) 5. Port "A" may be either left or right port. Port "B" is opposite from port "A". 71321X20 71421X20 Com'l Only 71321X25 71421X25 Com'l & Ind Symbol Parameter Test Condition Version Typ. Max. Typ. Max.
