The WR signal latches the state of the address control lines and the enable line. The RS signal clears both the address and enable data in the latches resulting in no output (all switches off). RS can be tied to the microprocessor reset pin. Extended Signal Range The enhanced LC2MOS processing results in a high breakdown and an increased analog signal range of VSS to VDD. Break-Before-Make Switching Switches are guaranteed break-before-make so that input signals are protected against momentary shorting. Low Leakage Leakage currents in the range of 20 pA make these multiplexers suitable for high precision circuits.
