Product details

Key specs and what they mean for your design

On-resistance of 17 Ohm max determines insertion loss and voltage drop through the switch. The 830 MHz bandwidth passes a 100 MHz clock or a 1080p video signal with minimal attenuation. Charge injection is 1.5 pC. Off-leakage is 2 nA max. Supply is fixed at 5 V single.

Package and temperature grade

Housed in a 16-pin QSOP (supplier device package 16-QSOP, 3.90 mm body width). Surface-mount only. The operating temperature range is -40 to 85 °C, industrial grade.

Lifecycle and sourcing

The QS4A205QG is listed as Active with RoHS3 compliance. No end-of-life notice or last-time-buy window has been issued. That means you can commit this part to a production BOM without worrying about obsolescence in the near term.
