Dual Retriggerable Monostable Multivibrator with Reset
The are dual retriggerable monostable multivibrators with output pulse width control by three methods: Once triggered, the basic output pulse width may be extended by retriggering the gated active LOW-going edge input na or the active HIGH-going edge input nb. Alternatively an output delay can be terminated at any time by a LOW-going edge on input nrd, which also dztasheet the triggering. An internal connection from nrd to the input gates makes it possible to trigger the circuit by a HIGH-going signal at input nrd as shown in Table 3.
Schmitt-trigger action in the na and nb inputs, makes the circuit highly tolerant to slower input rise and fall times. Ordering information Table 1. Functional diagram Product data sheet Rev January of Logic symbol Fig 3.

Dynamic characteristics Table 7. The output pulse width will only be extended when the time between the active-going edges of the trigger input pulses meets the minimum retrigger time. Measurement points are given in Table 8.
Propagation delays from inputs na, nb, nrd to outputs nq, nq and output transition times Product data sheet Rev January of Test circuit for measuring switching times Table 8. Timing component connections This output pulse can be eliminated using the circuit shown in Figure Power-up output pulse elimination circuit Product data sheet Rev January of When a system containing this device is powered-down or a rapid decrease of V CC to zero occurs, the monostable may sustain damage, due to the capacitor discharging through the input protection diodes.
To avoid this possibility, use a damping diode D EXT preferably a germanium or Schottky type diode able to withstand large current surges and connect as shown in Figure Power-down protection circuit Product data sheet Rev January of Package outline Fig Revision history Table Power dissipation capacitance condition for 74HCT is corrected.
