Overview
The NLAST9431MTR2G is a single-circuit analog switch manufactured by onsemi, classified under the interface category of analog switches, multiplexers, and demultiplexers. It features a Double Pole Double Throw (DPDT) switching circuit with a 2:2 configuration. The device operates within a single power supply voltage range of 2V to 5.5V. Key electrical parameters include a maximum on-resistance of 25 ohms and a channel-to-channel matching of 2 ohms. The -3dB bandwidth is specified at 200MHz, with turn-on and turn-off times of 14ns and 8ns respectively. Charge injection is 3pC, while off-state leakage current is limited to 1nA. Channel capacitance in the off state is 10pF for both CS and CD. The component is housed in a 16-WQFN package measuring 1.8x2.6mm and supports an operating temperature range from -55°C to 125°C.

Procurement Notes
Verify part authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for specific ordering suffixes if variant availability differs. Ensure storage conditions adhere to moisture sensitivity level requirements prior to assembly.
Selection Notes
Evaluate on-resistance and bandwidth requirements against application needs. Consider package size constraints for PCB layout. Verify voltage supply compatibility within the 2V to 5.5V range. Assess thermal management capabilities given the operating temperature limits.
Part Context
This component belongs to the NLAST94 series of analog switches from onsemi. It is designed for compact signal switching applications requiring low distortion and fast response times. The WQFN package facilitates surface mount technology integration.
Replacement Considerations
Check for pin-compatible alternatives within the same family or similar specifications from other manufacturers. Verify functional equivalence regarding voltage ranges and switching characteristics before substitution.
