74LVT574; 74LVTH574
3.3 V octal D-type flip-flop; 3-state
Rev. 04 -- 11 September 2008 Product data sheet
1. General description
The 74LVT574; 74LVTH574 is a high-performance product designed for VCC operation at 3.3 V. This device is an 8-bit, edge triggered register coupled to eight 3-state output buffers. The two sections of the device are controlled independently by the clock (pin CP) and output enable (pin OE) control gates. The state of each D input (one setup time before the LOW-to-HIGH clock transition) is transferred to the corresponding flip-flops Q output. The 3-state output buffers are designed to drive heavily loaded 3-state buses, MOS memories, or MOS microprocessors. The active LOW output enable (pin OE) controls all eight 3-state buffers independent of the clock operation. When pin OE is LOW, the stored data appears at the outputs. When pin OE is HIGH, the outputs are in the high-impedance OFF-state, which means they will neither drive nor load the bus.

The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. For SO20 packages: above 70 C derate linearly with 8 mW/K. For SSOP20 and TSSOP20 packages: above 60 C derate linearly with 5.5 mW/K. For DHVQFN20 packages: above 60 C derate linearly with 4.5 mW/K.

Typical values are measured at VCC = 3.3 V and Tamb = 25 C. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power. Unused pins at VCC or GND. This is the bus hold overdrive current required to force the input to the opposite logic state. 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 s is permitted. This parameter is valid for Tamb = 25 C only. ICC is measured with outputs pulled to VCC or GND. This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
