See additional discussion in the Operation section of the data sheet. 5Input resistance is code-dependent. 6Typicals represent average readings measured at 25 °C. 7All input control signals are specified with t R = tF = 2 ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V. 8The settling time specification does not apply for negative going transitions within the last 3 LSBs of ground. Specifications subject to change without notice. (@ VDD = 5 V, VSS = 0 V; or VDD = +5 V, VSS = –5 V, VREF = +2.5 V, –40 C < TA < +125 C, unless otherwise noted.) |
