permit positive or negative edge-triggered
monostable multivibrator action with retriggering
and external counting options. Inp uts include
+TRIGGER -TRIGGER, ASTABLE, ASTABLE,
RETRIGGER, an d EXTERNAL RESET. Buffered
outputs are Q, Q and OSCILLATOR. In all modes
of operation, an external capacitor must be
connected between C-Timing and RC-Common
terminals, and an external resistor must be
connected between the R-Timing and
RC-Common terminals.
For operating modes see functional terminal
connections and application notes.
