ADVANCE INFORMATION First Page of Data Sheet in Preparation MA AXIMM Quad SPST Analog Switches General Description The MXDG444/MXDG445 are quad single-pole-single- throw (SPST) analog switches. The MXDG444 is normally open (SPST, NO), while the MXDG445 is normally closed (SPST, NC). Both parts offer iow on resistance (85Q max) over the analog range, fast switching (120ns max), and low power dissipation (0.035mW max). Logic inputs are TTL compatible. The MXDG444/MXDG445 are designed with a +44V maximum breakdown voltage rating that allows +30V peak-to-peak switch-off blocking capacity. These switches can be used with a single positive supply (+5V to +30V) or split supplies (t5V to +20V) while retaining CMOS logic input compatibility and fast switching.
