This single expandable 2-2-2-2 AOI gate will reduce the boolean expression AB + CD + EF + GH + EXPAND, where EXPAND is the output from another AOI gate. 4086 = Single expandable 4-wide 2-input AND-OR-Invert (AOI).This dual 2-2 AOI gate will reduce the boolean expression AB + CD to 1st output and EF + GH to 2nd output. 4085 = Dual 2-wide 2-input AND-OR-Invert (AOI).The 4572 has a NOR gate and NAND gate (see above). The 4048 is an 8-input gate too (see below). Note: The 4068 & 4078 has two outputs Q and Q. 40107 = Dual 2-Input NAND (136 mA open drain outputs) ( DIP-8 package).4093 = Quad 2-Input NAND ( schmitt trigger inputs) (pinout compatible with 4011).

4050 = Hex Buffer (outputs can drive two TTL / four 74LS / eight CMOS loads) (VDD power rail pin at non-typical location).4041 = Quad Buffer/Inverter (each input has 2 outputs Q and Q) (outputs can drive one TTL / two 74LS / four CMOS loads).4504 = Hex Buffer (dual power rails) (logic can step up or down, depending on power rail choice).40109 = Quad Buffer (dual power rails) (logic can step up or down, depending on power rail choice).Since there are numerous 4000-series parts, this section groups related combinational logic parts to make it easier for the reader to choose part numbers.Īll parts in this section have normal inputs and push-pull outputs, unless stated differently.

However, other manufacturers use different prefixes and suffixes on their part numbers, and not all devices are available from all sources or in all package sizes. Due to the popularity of these parts, other manufacturers released pin-to-pin compatible logic devices and kept the 4000 sequence number as an aid to identification of compatible parts. The earlier datasheets included the internal schematics of the gate architectures and a number of novel designs are able to 'mis-use' this additional information to provide semi-analog functions for timing skew and linear signal amplification. Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (generally 3V to 15V, some devices higher ) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue electronics, where the slower operation may be an EMC advantage. In 1968, the original 4000-series was introduced by RCA. The following is a list of CMOS 4000-series digital logic integrated circuits.
