the cd4013 is a dual d-type flip-flop that features independent set-direct input (sd), clear-direct input (cd), clock input (cp) and outputs (q,q). data is accepted when cp is low and is transferred to the output on the positive-going edge of the clock. the active high asynchronous cd and sd inputs are independent and override the d or cp inputs. the outputs are buffered for best system performance. the clock input’s schmitt-trigger action makes the circuit highly tolerant of slower clock rise and fall times.
it operates over a recommended vdd power supply range of 3v to 15v referenced to vss (usually ground). unused inputs must be connected to vdd, vss, or another input.
