Support is limited to customers who have already adopted these products. CD4013BMS consists of two identical, independent data type flip-flops. Each flip-flop has independent data, set, reset, and clock inputs and Q and Q outputs. These devices can be used for shift register applications, and, by connecting Q output to the data input, for counter and toggle applications. The logic level present at the D input is transferred to the Q output during the positive going transition of the clock pulse. Setting or resetting is independent of the clock and is accomplished by a high level on the set or reset line, respectively. The CD4013BMS is supplied in these 14 lead outline packages: Braze Seal DIP H4Q Frit Seal DIP H1B Ceramic Flatpack H3W
