mc14538b http://onsemi.com 8 trigger operation the block diagram of the mc14538b is shown in figure 1, with circuit operation following. as shown in figure 1 and 10, before an input trigger occurs, the monostable is in the quiescent state with the q output low, and the timing capacitor c x completely charged to v dd . when the trigger input a goes from v ss to v dd (while inputs b and reset are held to v dd ) a valid trigger is recognized, which turns on comparator c1 and n ? channel transistor n1 ? . at the same time the output latch is set. with transistor n1 on, the capacitor c x rapidly discharges toward v ss until v ref1 is reached. at this point the output of comparator c1 changes state and transistor n1 turns off. comparator c1 then turns off while at the same time comparator c2 turns on. w ith transistor n1 off, the capacitor c x begins to charge through the timing resistor, r x , toward v dd . when the voltage across c x equals v ref 2 , comparator c2 changes state, causing the output latch to reset (q goes low) while at the same time disabling comparator c2 ? . this ends at the timing cycle with the monostable in the quiescent state, waiting for the next trigger. in the quiescent state, c x is fully charged to v dd causing the current through resistor r x to be zero. both comparators are ?off? with total device current due only to reverse junction leakages. an added feature of the mc14538b is that the output latch is set via the input trigger without regard to the capacitor voltage. thus, propagation delay from trigger to q is independent of the value of c x , r x , or the duty cycle of the input waveform. retrigger operation the mc14538b is retriggered if a valid trigger occurs ? followed by another valid trigger ? before the q output has returned to the quiescent (zero) state. any retrigger, after the timing node voltage at pin 2 or 14 has begun to rise from v ref 1 , but has not yet reached v ref 2 , will cause an increase in output pulse width t. when a valid retrigger is initiated ? , the voltage at c x /r x will again drop to v ref 1 before progressing along the rc charging curve toward v dd . the q output will remain high until time t, after the last valid retrigger. reset operation the mc14538b may be reset during the generation of the output pulse. in the reset mode of operation, an input pulse on reset sets the reset latch and causes the capacitor to be fast charged to v dd by turning on transistor p1 ? . when the voltage on the capacitor reaches v ref 2 , the reset latch will clear, and will then be ready to accept another pulse. it the reset input is held low, any trigger inputs that occur will be inhibited and the q and q outputs of the output latch will not change. since the q output is reset when an input low level is detected on the reset input, the output pulse t can be made significantly shorter than the minimum pulse width specification. power ? down considerations large capacitance values can cause problems due to the large amount of energy stored. when a system containing the mc14538b is powered down, the capacitor voltage may discharge from v dd through the standard protection diodes at pin 2 or 14. current through the protection diodes should be limited to 10 ma and therefore the discharge time of the v dd supply must not be faster than (v dd ). (c) / (10 ma). for example, if v dd = 10 v and c x = 10 f, the v dd supply should discharge no faster than (10 v) x (10 f) / (10 ma) = 10 ms. this is normally not a problem since power supplies are heavily filtered and cannot discharge at this rate. when a more rapid decrease of v dd to zero volts occurs, the mc14538b can sustain damage. to a void this possibility use an external clamping diode, d x , connected as shown in fig. 11. figure 11. use of a diode to limit power down current surge v ss d x v dd v dd r x c x q q reset
