therefore the shift of the low level at the CS input) is very small (typ. 40mV). When the chip select line is

switched high again by the processor, the transistor Q

gain is negligible); the diode D

failure the TL7705B is triggered and its RESET output becomes low. The base of transistor Q

longer draw current. Thus the CS input of the memory is separated from the chip select line.
