22 / 39 page R1QBA72 / R1QEA72 Series Rev. 0.11 : 2013.01.15 PAGE:22 Common AC Operating Conditions Parameter Symbol Min Typ Max Unit Notes Input high voltage V IH (AC) V REF + 0.2 ⎯⎯ V 1, 2, 3, 4 Input low voltage V IL (AC) ⎯⎯ V REF – 0.2 V 1, 2, 3, 4 Notes: 1. All voltages referenced to V SS (GND). During normal operation, V DDQ must not exceed VDD. 2. These conditions are for AC functions only, not for AC parameter test. 3. Overshoot: V IH (AC) ≤ VDDQ + 0.5 V for t ≤ tKHKH/2 Undershoot: V IL (AC) ≥−0.5 V for t ≤ tKHKH/2 Control input signals may not have pulse widths less than t KHKL (min) or operate at cycle rates less than t KHKH (min). 4. To maintain a valid level, the transitioning edge of the input must: a. Sustain a constant slew rate from the current AC level through the target AC level, V IL (AC) or VIH (AC). b. Reach at least the target AC level. c. After the AC target level is reached, continue to maintain at least the target DC level, V IL (DC) or VIH (DC). Output load conditions Output load and voltage conditions 50 Ω ZQ Q V REF 250 Ω Z 0 = 50Ω SRAM V DDQ / 2 = 0.75V V DDQ / 2 = 0.75V V DD V DDQ V SS 1.8V ±0.1V 1.5V R10DS0181EJ0011 |
