| Features |
power supply. The separate chip select input (CS) allows simple memory expansion when the outputs are wire-O Red. If CS is HIGH, the outputs are floating and no new information can be written into the memory. The signal at O has the same polarity as the data input D, while the signal at O is the complement of the signal at O. The write control W must be HIGH for writing into the memory.
