3 Input Nand Gate Cmos. Cd4011b cd4012b and cd4023b nand gates provide the system designer with direct implementation of the nand function and supplement the existing family of cmos gates. As with the ttl nand gate the cmos nand gate circuit may be used as the starting point for the creation of an and gate.

Cd4011b cd4012b and cd4023b nand gates provide the system designer with direct implementation of the nand function and supplement the existing family of cmos gates.
The following sequence of illustrations shows the behavior of this nand gate for all four possibilities of input logic levels 00 01 10 and 11.
It consists of series combination of three nmos transistors that conducts when all the inputs are high and pulls the output f to low level. Due to the popularity of these parts other manufacturers released pin to pin compatible logic devices and kept the 7400 sequence number as an aid to identification of. Click the input switches or type the a b and c d e bindkeys to control the gates. Open in new find other nand gate description.
