TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 10.1 Application Information A low level at the preset (PRE) or clear (CLR) input sets or resets the outputs, regardless of the levels of the other inputs. When PRE and CLR are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not related directly to the rise time of the clock pulse. Following the hold-time interval, dataattheDinputcanbechangedwithoutaffectingthelevelsattheoutputs. The resistor and capacitor at the CLR pin are optional. If they are not used, the CLR pin should be connected directlytoV tobeinactive.

Each V terminal should have a good bypass capacitor to prevent CC powerdisturbance.Fordeviceswithasinglesupply,a0.1-μFcapacitorisrecommendedandiftherearemultiple V terminals then .01-μF or .022-μF capacitors are recommended for each power terminal. It is acceptable to CC parallel multiple bypass caps to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible forbestresults.

SN74LVC1G74 SCES794E–OCTOBER2009–REVISEDJANUARY2015 www.ti.com 12 Layout 12.1 Layout Guidelines When using multiple bit logic devices, inputs should not float. In many cases, functions or parts of functions of digital logic devices are unused. Some examples are when only two inputs of a triple-input AND gate are used, or when only 3 of the 4-buffer gates are used. Such input pins should not be left unconnected because the undefinedvoltagesattheoutsideconnectionsresultinundefinedoperationalstates. Specified in Figure 7 are rules that must be observed under all circumstances. All unused inputs of digital logic devices must be connected to a high or low bias to prevent them from floating. The logic level that should be applied to any particular unused input depends on the function of the device. Generally they will be tied to GND or V , whichever makes more sense or is more convenient. It is acceptable to float outputs unless the part is a CC transceiver. If the transceiver has an output enable pin, it will disable the outputs section of the part when asserted.ThiswillnotdisabletheinputsectionoftheI/Ossotheyalsocannotfloatwhendisabled. 12.2 Layout Example V cc Input Unused Input Output Unused Input Output Input Figure7.
