5 / 24 page  Data Sheet ADM3055E/ADM3057E Rev. A | Page 5 of 24 TIMING SPECIFICATIONS All voltages are relative to their respective ground. 4.5 V ≤ VCC ≤ 5.5 V, 1.7 V ≤ VIO ≤ 5.5 V, TMIN to TMAX, and STBY low, unless otherwise noted. Typical specifications are at VCC = VIO = 5 V and TA = 25°C, unless otherwise noted. Table 2.
