Table 16. Asynchronous Read AC Characteristics (1)

(TA = –40 to 125°C; VDD =5V ± 10% and VDDQ = 3.3V ± 0.3V)

Note: 1. See AC Testing Measurements Conditions for timing measurements.

2. Sampled only, not 100% tested.

3. G may be delayed up to tELQV-tGLQV after falling edge of E without increasing tELQV.
