Product data sheet
12.1 Timing component connections
12.2 Power-up considerations
The basic output pulse width is essentially determined by the values of the external timing
components R
When the monostable is powered-up it may produce an output pulse, with a pulse width
defined by the values of R
circuit shown in
Fig 13. Timing component connections
Fig 14. Power-up output pulse elimination circuit
(1) For minimum noise generation it is recommended to ground pins 6 (2CEXT) and 14 (1CEXT)
externally to pin 8 (GND).
