With regard to the SR Latch truth table, when the Set input is driven HIGH, the pin connected to the Q bar output of the latch will be driven LOW. If the Reset input is driven HIGH, the pin connected to the Q bar output will be driven HIGH. When both Set and Reset inputs are HIGH, the operation of the Latch will be in Reset mode since this Latch is Reset dominant. When both inputs are driven LOW, the outputs of the Latch will hold the last known output values. This is important in the operation of the relaxation oscillator design.
