Product data sheet Rev. 04 — 11 September 2008 6 of 16 NXP Semiconductors 74LVT574; 74LVTH574 3.3 V octal D-type flip-flop; 3-state [1] Typical values are measured at VCC = 3.3 V and Tamb =25 °C. [2] For valid test results, data must not be loaded into the flip-flops (or latches) after applying power. [3] Unused pins at VCC or GND. [4] This is the bus hold overdrive current required to force the input to the opposite logic state. [5] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V a transition time of 100 µs is permitted. This parameter is valid for T amb =25 °C only. [6] ICC is measured with outputs pulled to VCC or GND. [7] This is the increase in supply current for each input at the specified voltage level other than VCC or GND. 10.
