They perform the BooleanfunctionY= Ainpositivelogic. Schmitt-Trigger inputs are designed to provide a minimum separation between positive and negative switching thresholds. This allows for noisy or slow inputs that would cause problems such as oscillation or excessive currentdrawwithnormalCMOSinputs. 8.2 Functional Block Diagram A Y Copyright © 2016,Texas Instruments Incorporated 8.3 Feature Description Thedevicecanoperatefromveryslowtransitionedgeinputs.Thisdevicehashighnoiseimmunity. 8.4 Device Functional Modes Table1liststhefunctionalmodesoftheSNx414andSNx4LS14.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information The SNx414 and SNx4LS14 device is a Schmitt-Trigger input CMOS device that can be used for a multitude of inverting buffer type functions. The application shown here takes advantage of the Schmitt-Trigger inputs to produceadelayforalogicinput. 9.2 Typical Application Copyright © 2016, Texas Instruments Incorporated Figure28. SimplifiedApplicationSchematic 9.2.1 DesignRequirements This device uses CMOS technology. Take care to avoid bus contention because it can drive currents that would exceed maximum limits. Parallel output drive can create fast edges into light loads, so consider routing and load conditionstopreventringing. 9.2.2 DetailedDesignProcedure This circuit is designed around an RC network that produces a slow input to the second inverter. The RC time constant(τ)iscalculatedfrom: τ=RC. The delay time for this circuit is from t = –ln |1 – V / V | τ to t = –ln |1 – V / V | τ. It delay(min) T+(min) CC delay(max) T+(max) CC must be noted that the delay is consistent for each device, but because the switching threshold is only ensured between the minimum and maximum value, the output pulse length varies between devices. These values must becalculatedbyusingtheminimumandmaximumensuredV valuesintheElectricalCharacteristics.

SN5414,SN54LS14,SN7414,SN74LS14 www.ti.com SDLS049C–DECEMBER1983–REVISEDNOVEMBER2016 10 Power Supply Recommendations The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Recommended Operating Conditions. The V terminal must have a good bypass capacitor to prevent power CC disturbance. TI recommends using a 0.1-µF capacitor on the V terminal, and must be placed as close as CC possibletothepinforbestresults. 11 Layout 11.1 Layout Guidelines When using multiple bit logic devices, inputs must never float. In many cases, functions or parts of functions of digital logic devices are unused, for example, when only two inputs of a triple-input AND gate are used or only three of the four buffer gates are used. Such inputs must not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. 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 must be applied to any particular unused input depends on the function of the device. Generally they are tied to GND or V , whichever makes more sense or is more convenient. Floating outputs are generally acceptable, unless the CC partisatransceiver. 11.2 Layout Example V cc Input Unused Input Output Unused Input Output Input Figure35.

PACKAGE OPTION ADDENDUM www.ti.com 28-Jul-2020 (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width.
