Part details & applications

The MAX334 is a quad single-pole-single-throw, normally closed (SPST, NC) analog switch, pin compatible with the Harris Hl-201 HS and Siliconix DG2n The MAX334 has guaranteed break-before-make switching (t_OFF < t_ON), while featuring fast switching speeds. Turn-on time is less than 100ns and turn-off time is less than 50ns; channel on resistance is 50 ohms maximum. CMOS inputs provide reduced input loading and very low leakage currents.

The MAX334 is also a direct replacement for the DG201 and DG211, featuring ¼ the on resistance and five times the speed.

The MAX334 may be used with split supplies ( ±5V to ±15V) or single positive supplies (+5V to +30V) while retaining CMOS and TTL logic compatible inputs, and maintaining high switching speed.
