**Complementary metal–oxide–semiconductor)**chips time and again.

I am an analog addict but I must say that the digital 4000 series is very versatile.

It's hard to keep track of what each chip is capable of so I've decided to start a list.

(Ive also added a few other CMOS chips that don't belong in the 4000 range, but are still useful)

I hope this list will become useful as it grows over the coming years.

40106 - hex schmitt trigger inverters.

This can make 6 square wave oscillators

4001 - Quad two-input NOR gate (four NOR gates), (NLC Bools)

4006 - shift register

4009 - Hex inverter (six NOT gates)

4011 - Quad two-input NAND gate (four NAND gates), (NLC Bools)

4015 - shift register

4016 - analog bilateral switch

4017 - decade counter (Squid axon),

(1050 mix sequencer)

Baby 10 sequencer.

4024 - shift register

4029 - 4 stage counter-binary/decade (NLC 4SEQ)

(NLC 32:1)

4030 - Quad two-input XOR gate (four XOR gates), (NLC Bools)

4040 - divider/ripple counter

4046 - PLL (Phase Locked Loop), built in VCO, (NLC Vactrol Pill)

4051 - Eight channel multiplexer

4052 - Dual 4 channel multiplexer, (NLC 4SEQ)

4060 - Has a built in oscillator

4066 - quad bilateral switch

4093 - quad schmitt trigger/ NAND gates (can make 4 square wave oscillators.)

4094 - 8 stage serial shift register (8bitcipher)

4096 - shift register

4051 - multiplexer

4070 - XOR gate (NLC Bools)

4071 - Quad two-input OR gate (four OR gates) (NLC Bools)

(1050 mix sequencer)

4077 - Quad two-input XNOR gate (four XNOR gates), (NLC Bools)

4081 - Quad two-input AND gate (four AND gates), (NLC Bools)

(1050 mix sequencer)

In vintage synths the most popular of the 4000-series chips appear to be

the analog bilateral switches (4016, 4066), the analog multiplexer/demultiplexers

4051, 4052,4053, 4067) and the 4046 phase-locked loop (PLL). These allow the routing of analog control signals.

The 4046 PLL was used in such machines as the OSCar.

The CMOS synth was also made famous by Stanley Lunetta of Sacramento who passed away on March 3, 2016.

His Lunetta Synth inspired the DIY synthesizer community. He used mainly 4000 series CMOS chips.

Experimentation really is the whole point. Learning what the different types of logic chips do, and making use of them in interesting ways.
