NLAS9431 Low Voltage Single Supply Dual DPDT Analog Switch
The NLAS9431 is an advanced dual-independent CMOS double pole-double throw (DPDT) analog switch fabricated with silicon gate CMOS technology. It achieves high speed propagation delays and low ON resistances while maintaining CMOS low power dissipation. This DPDT controls analog and digital voltages that may vary across the full power-supply range (from VCC to GND). The device has been designed so the ON resistance (RON) is much lower and more linear over input voltage than RON of typical CMOS analog switches. The channel select input is compatible with standard CMOS outputs. The channel select input structure provides protection when voltages between 0 V and 5.5 V are applied, regardless of the supply voltage. This input structure helps prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc. The NLAS9431 can also be used as a quad 2-to-1 multiplexer- demultiplexer analog switch with two Select pins that each controls two multiplexer-demultiplexers.

Channel switch control/s test socket is normalized. Off isolation is measured across an off channel. On loss is the bandwidth of an On switch. VISO, Bandwidth and VONL are independent of the input signal direction. VISO = Off Channel Isolation = 20 Log VONL = On Channel Loss = 20 Log VOUT VIS for VIN at 100 kHz VOUT for VIN at 100 kHz to 50 MHz VIS
Bandwidth (BW) = the frequency 3 dB below VONL VCT = Use VISO setup and test to all other switch analog input/outputs terminated with 50 W
