TAP DC electrical characteristics and operating conditions
(+10oC < TJ < +110
oC and +2.4V < V
DD < +2.6V unless otherwise noted)
1. All voltage referenced to VSS(GND).
2. Overshoot: VIH(AC) ≤ VDD + 1.5V for t ≤
tKHKH/2
Undershoot:VIL(AC) ≥ -0.5 for t ≤
tKHKH/2
Power-up:
VIH ≤ +2.6V and VDD ≤ 2.4V and VDDQ ≤ 1.4V for t ≤ 200ms
During normal operation, VDDQ must not exceed VDD. Control input signals (such as LD, R/W, etc.) may not have pulsed widths less than
tKHKL(Min) or operate at frequencies exceeding fKF(Max).
