Overview
The NLAS4599DFT2 is an advanced high-speed CMOS single pole - double throw (SPDT) analog switch fabricated with silicon gate CMOS technology. It is designed to achieve high-speed propagation delays and low ON resistances while maintaining low power dissipation. This switch can control both analog and digital voltages that may vary across the full power-supply range (from VCC to GND). The device is particularly notable for its low ON resistance (RON), which is more linear over input voltage compared to typical CMOS analog switches. The channel select input is compatible with standard CMOS outputs and features over-voltage tolerance up to 5.5 V, protecting against supply voltage - input/output voltage mismatch, battery backup, and hot insertion.
