DG444DY

4路,TTL输入

The DG444 and DG445 monolithic CMOS analog switches are drop-in replacements for the popular DG211 and DG212 series devices. They include four independent single pole single throw SPST analog switches and TTL and CMOS compatible digital inputs.

These switches feature lower analog ON resistance <85Ω and faster switch time tON <250ns compared to the DG211 and DG212. Charge injection has been reduced, simplifying sample and hold applications.
