Inputs include + TRIGGER, - TRIGGER, ASTABLE, ASTABLE, RETRIGGER and MR (Master Reset). Buffered outputs are O, O and OSCILLATOR OUTPUT. In all modes of operation an external capacitor (C ) must be t connected between C and RC , and an external TC TC resistor (R ) must be connected between R and t TC RC (continued on next page).
