#635 CD4001 SR Latch
Set-Reset latch implemented with CD4001 NOR gates.
Here’s a quick demo..
This circuit is another implementation of a Set-Reset flip-flop, this time using NOR gates. Sometimes this is referred to as a “NOR Latch”. A CD4001 is used to provide the two NOR gates required.
See the LEAP#061 SRLatch circuit for an implementation using BJTs.
Ben Eater has a great video explaining SR latch behaviour:
