The CD4011B, CD4012B, and CD4023B are NAND gates provide the system designer with direct implementation of the NAND function and supplement the existing family of CMOS gates. All inputs and outputs are buffered IC SOP-14 Pins Package.
The CD4013BT are 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 IC SOP-14 Pins Package.
The CD4020BM, CD4020BE, are ripple-carry binary counters. All counter stages are master-slave flip-flops state of a counter advances one count on the negative transition of each input pulse a high level on the RESET line resets the counter to its all zero
The CD4021BM series types are supplied in 16-lead hermetic dual-in-line ceramic packages (D and F suffixes), 16-lead dual-in-line plastic packages (E suffix), and in chip form (H suffix).
