Each multivibrator has a CC negative-transition-triggered (A) input and a positive-transition-triggered (B) input, either of which can be used as aninhibitinput. This edge-triggered multivibrator features output pulse-duration control by three methods. In the first method, the A input is low and the B input goes high. In the second method, the B input is high and the A input goes low. In thethirdmethod,theAinputislow,theBinputishigh,andtheclear(CLR)inputgoeshigh. The output pulse duration is programmable by selecting external resistance and capacitance values. The external timing capacitor must be connected between C and R /C (positive) and an external resistor ext ext ext connected between R /C and V . To obtain variable pulse durations, connect an external variable resistor ext ext CC betweenR /C andV .TheoutputpulsedurationalsocanbereducedbytakingCLRlow. ext ext CC Pulse triggering occurs at a particular voltage level and is not related directly to the transition time of the input pulse. The A, B, and CLR inputs have Schmitt triggers with sufficient hysteresis to handle slow input transition rateswithjitter-freetriggeringattheoutputs. Once triggered, the outputs are independent of further transitions of the A and B inputs and are a function of the timing components, or the output pulses can be terminated by the overriding clear. Input pulses can be of any duration relative to the output pulse. Output pulse duration can be varied by choosing the appropriate timing components. Output rise and fall times are TTL compatible and independent of pulse duration. Typical triggering andclearingsequencesareillustratedintheinput/outputtimingdiagram. The variance in output pulse duration from device to device typically is less than ±0.5% for given external timing components. An example of this distribution for the SN74LV221A-Q1 is shown in Figure 8. Variations in output pulsedurationversussupplyvoltageandtemperatureareshowninFigure5. During power up, Q outputs are in the low state, and Q outputs are in the high state. The outputs are glitch free, withoutapplyingaresetpulse. This device is fully specified for partial-power-down applications using I .

SN74LV221A-Q1 SCLS692A–OCTOBER2005–REVISEDAPRIL2008 www.ti.com APPLICATION INFORMATION CautioninUse To prevent malfunctions due to noise, connect a high-frequency capacitor between V and GND, and keep the CC wiringbetweentheexternalcomponentsandC andR /C terminalsasshortaspossible. ext ext ext Power-DownConsiderations Large values of C can cause problems when powering down the SN74LV221A-Q1 because of the amount of ext energy stored in the capacitor. When a system containing this device is powered down, the capacitor can discharge from V through the protection diodes at pin 2 or pin 14. Current through the input protection diodes CC must be limited to 30 mA; therefore, the turn-off time of the V power supply must not be faster than CC t = V × C /30 mA. For example, if V = 5 V and C = 15 pF, the V supply must turn off no faster than CC ext CC ext CC t = (5 V) × (15 pF)/30 mA = 2.5 ns. Usually, this is not a problem because power supplies are heavily filtered and cannot discharge at this rate. When a more rapid decrease of V to zero occurs, the SN74LV221A-Q1 can CC sustaindamage.Toavoidthispossibility,useexternalclampingdiodes.
