Dual retriggerable monostable multivibrator with reset
[1]
tpd is the same as tPHL and tPLH; tt is the same as tTHL and tTLH
[2]
For other REXT and CEXT combinations see Figure 7. If CEXT > 10 nF, the next formula is valid.
tW =K × REXT × CEXT, where:
tW = typical output pulse width in ns;
REXT = external resistor in kΩ;
CEXT = external capacitor in pF;
K = constant = 0.45 for VCC = 5.0 V and 0.55 for VCC = 2.0 V.
The inherent test jig and pin capacitance at pins 15 and 7 (nREXT/CEXT) is approximately 7 pF.
[3]
The time to retrigger the monostable multivibrator depends on the values of REXT and CEXT. 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. If CEXT >10 pF,
the next formula (at VCC = 5.0 V) for the setup time of a retrigger pulse is valid:
trtrig = 30 + 0.19 × REXT × CEXT0.9 +13 × REXT1.05, where:
trtrig = retrigger time in ns;
CEXT = external capacitor in pF; REXT = external resistor in kΩ.
The inherent test jig and pin capacitance at pins 15 and 7 (nREXT/CEXT) is 7 pF.
[4]
When the device is powered-up, initiate the device via a reset pulse, when CEXT <50pF.
[5]
CPD is used to determine the dynamic power dissipation (PD in µW).
PD =CPD × VCC2 × fi + ∑(CL × VCC2 × fo) + 0.75 × CEXT × VCC2 × fo +D × 16 × VCC where:
fi = input frequency in MHz;
fo = output frequency in MHz;
D = duty factor in %;
CL = output load capacitance in pF;
VCC = supply voltage in V;
CEXT = timing capacitance in pF;
∑(CL × VCC2 × fo) sum of outputs.
