LM341/LM78MXX Series3-Terminal Positive Voltage RegulatorsGeneral DescriptionThe LM341and LM78MXX series of three-terminal positive voltage regulators employ built-in current limiting,thermal shutdown,and safe-operating area protection which makes them virtually immune to damage from output overloads.With adequate heatsinking,they can deliver in excess of 0.5A output current.Typical applications would include local (on-card)regulators which can eliminate the noise and de-graded performance associated with single-point regulation.Featuresn Output current in excess of 0.5A n No

Performance Characteristics(Continued)Design ConsiderationsThe LM78MXX/LM341XX fixed voltage regulator series has built-in thermal overload protection which prevents the de-vice from being damaged due to excessive junction tem-perature.The regulators also contain internal short-circuit protection which limits the maximum output current,and safe-area pro-tection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is in-creased.Although the internal power dissipation is automatically lim-ited,the maximum junction temperature of the device must be kept below +125˚C in order to meet data sheet specifica-tions.An adequate heatsink should be provided to assure this limit is not exceeded under worst-case operating condi-tions (maximum input voltage and load current)if reliable performance is to be obtained).1.0Heatsink ConsiderationsWhen an integrated circuit operates with appreciable cur-rent,its junction temperature is elevated.It is important to quantify its thermal limits in order to achieve acceptable per-formance and reliability.This limit is determined by summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating envi-ronment.A one-dimension steady-state model of conduction heat transfer is demonstrated in The heat generated at thedevice junction flows through the die to the die attach pad,through the lead frame to the surrounding case material,to the printed circuit board,and eventually to the ambient envi-ronment.Below is a list of variables that may affect the ther-mal resistance and in turn the need for a heatsink.R θJC (Component Variables)R θCA (Application Variables)Leadframe Size &Material Mounting Pad Size,Material,&LocationNo.of

LM78MXX/LM341XX regulators have internal thermal shutdown to protect the device from over-heating.Under all possible operating conditions,the junction temperature of the LM78MXX/LM341XX must be within the range of 0˚C to 125˚C.A heatsink may be required depending on the maxi-mum power dissipation and maximum ambient temperature of the application.To determine if a heatsink is needed,the power dissipated by the regulator,P D ,must be calculated:I IN =I L +I GP D =(V IN −V OUT )I L +V IN I Gshows the voltages and currents which are present in the circuit.The next parameter which must be calculated is the maxi-mum allowable temperature rise,T R (max):θJA =TR (max)/P D If the maximum allowable value for θJA ˚C/w is found to be ≥60˚C/W for TO-220package or ≥92˚C/W for TO-252pack-age,no heatsink is needed since the package alone will dis-sipate enough heat to satisfy these requirements.If the cal-culated value for θJA fall below these limits,a heatsink is required.As a design aid,Table 1shows the value of the θJA of TO-252for different heatsink area.The copper patterns that we used to measure these θJA are shown at the end of the Application Note Section.reflects the same test results as what are in the Table 1shows the maximum allowable power dissipation vs.ambi-ent temperature for theTO-252device.shows the maximum allowable power dissipation vs.copper area (in 2)for

A count enable input serves as the carry/borrowinput in multi-stage counters. Control input, Down/Up, determines whether a circuit counts up or down. A MAX/MIN output and a Ripple Clock output provide overflow/underflow indication and make possible a variety of methods for generating carry/borrow signals in multi-stage counter applications.All inputs are equipped with protection circuits against static discharge and transient excess voltage.M74HC1914 BIT SYNCHRONOUS UP/DOWN COUNTERSPIN CONNECTION AND IEC LOGIC SYMBOLSORDER CODESPACKAGE TUBE T & RDIP M74HC191B1R SOP M74HC191M1RM74HC191RM13TR TSSOPM74HC191TTRM74HC1912/14INPUT AND OUTPUT EQUIVALENT CIRCUITPIN DESCRIPTIONTRUTH TABLEa - d : The level of steady state inputs a through d respectivelyPIN No SYMBOL NAME AND FUNCTION3, 2, 6, 7QA to QDFlip-Flop Outputs 4ENABLECount Enable Input(Active LOW)5U/D Parallel Data Input 11LOAD Load Input (Active LOW)12MA/MI OUT Terminal Count Output13RCRipple Clock Output(Active LOW)14CLOCKClock Input (LOW toHIGH, edge triggered)15, 1, 10, 9DA to DD Data Inputs 8GND Ground (0V)16Vcc Positive Supply VoltageM74HC191 LOGIC DIAGRAM3/14M74HC1914/14TIMING CHARTABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond which damage to the device may occur.
