Is it advisable to make our own S-R latch using NAND gates? Is it stable and reliable? Or do you prefer to use S-R ICs like 74hc279? If there is no problem doing it with NAND gates, then i will save one IC and more importantly board space. Thanks.
It also depends upon what you actually wnat to do...if you intend to make a bigger project of which SR latch is only a small part...then what is the need to consume more space and money by making SR latch discretely
