The NLAST4599 is an advanced high-speed CMOS single-die - double-die analog switch manufactured in a silicon gate CMOS process. It enables high speed propagation delay and low on-resistance while maintaining low power consumption. The switch controls analog and digital voltages that vary over the full power supply range from VCC to GND. The device design has a much lower on-resistance (RON) than traditional CMOS analog switches and is more linear based on the input voltage. The -channel select input is compatible with TTL levels. The -channel select input structure provides protection when applying voltages from 0 - 5.5 V, regardless of the supply voltage. This input structure helps prevent device damage due to supply voltage - input/output voltage mismatch, battery backup, thermal insertion, etc.
