The following is a list of CMOS 4000-series digital logic integrated circuits. In 1968, the original 4000-series was introduced by RCA. Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue electronics, where the slower operation may be an EMC advantage. 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.^[1] 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. 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.

Logic gates

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.

All parts in this section have normal inputs and push-pull outputs, unless stated differently.

One input voltage translation gates:

• 40109 = Quad Buffer (dual power rails) (logic can step up or down, depending on power rail choice)
• 4504 = Hex Buffer (dual power rails) (logic can step up or down, depending on power rail choice)

One input logic gates:

• 4041 = Quad Buffer/Inverter, each input has 2 outputs Q and Q (outputs can drive one TTL / two 74LS / four CMOS loads)
• 4050 = Hex Buffer (outputs can drive two TTL / four 74LS / eight CMOS loads) (note: VDD power rail pin at non-typical location)
• 4049 = Hex Inverter (outputs can drive two TTL / four 74LS / eight CMOS loads) (note: VDD power rail pin at non-typical location)
• 4069 = Hex Inverter
• 40106 = Hex Inverter with schmitt trigger inputs (pinout compatible with 4069)
• 4572 = Quad Inverter, plus a 2-Input NOR gate and a 2-Input NAND gate (both can be converted into inverters)

Two to eight input logic gates:

• 4093 = Quad 2-Input NAND with schmitt trigger inputs (pinout compatible with 4011)
• 40107 = Dual 2-Input NAND with open drain outputs (can drive 32 CMOS loads) (DIP-8 package)

Configuration	AND	NAND	OR	NOR	XOR	XNOR
Quad 2-Input	4081	4011	4071	4001	4070	4077
Triple 3-Input	4073	4023	4075	4025	n/a	n/a
Dual 4-Input	4082	4012	4072	4002	n/a	n/a
Single 8-Input	4068	4068	4078	4078	n/a	n/a

Note: The 4068 & 4078 has two outputs Q and Q. The 4048 is an 8-input gate too (see below). The 4572 has a NOR gate and NAND gate (see above).

AND-OR-Invert (AOI) logic gates:

• 4085 = Dual 2-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.
• 4086 = Single expandable 4-wide 2-input AND-OR-Invert (AOI). 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.
• 4048 = Single expandable 8-input 8-function with three-state output, 8 choices for gate type: 8 NOR / 8 OR / 8 NAND / 8 AND / 4-4 AND-OR-Invert / 4-4 AND-OR / 4-4 OR-AND-Invert / 4-4 OR-AND

When configured as AND-OR-INVERT (AOI) gate, it will reduce the boolean expression ABCD + EFGH + EXPAND.

When configured as AND-OR (AO) gate, it will reduce the boolean expression ABCD + EFGH + EXPAND.

When configured as NOR gate, it will reduce the boolean expression A + B + C + D + E + F + G + H + EXPAND, which is a 9-input NOR gate when EXPAND is used as a 9th input.

When configured as OR gate, it will reduce the boolean expression A + B + C + D + E + F + G + H + EXPAND, which is a 9-input OR gate when EXPAND is used as a 9th input.

Note: The 4041 can simplify AOI boolean expression implementations by providing buffered A, B, C, D and A, B, C, D.

Parts list

This list consists mostly of part numbers from a 1983 RCA databook, though the leading "CD" and tailing letters (A, B, UB) have been removed for generic part number use. The numeric portion of part numbers from some manufactures may not be identical to generic part numbers in this table. Motorola typically prepended a "1" and removed the first "0" from part numbers within the range of 40100 to 40199, such as RCA CD40174B becomes Motorola MC14174B.
