  5. LM393 This output stage requires a pull-up resistor for most applications

  6. - + Relaxation Oscillator Pullup resistor (required for most LM393 comparator circuits) Generic Dual-Supply Implementation Single-Supply LM393 Implementation R1 R2 V+ +Vs -Vs V- C R Voltage at this node sets triggering point. Additional 100k resistor to V+ is required because the low outptu state is 0V, not –Vs as in the dual supply implementation.
