PRODUCT HIGHLIGHTS GENERAL DESCRIPTION The ADG741/ADG742 are monolithic CMOS SPST switches. 1. 1.8 V to 5.5 V Single-Supply Operation. The ADG741/ADG742 offer high performance, including These switches are designed using an advanced submicron low on resistance and fast switching times. They are fully process that provides low power dissipation, yet offers high specified and guaranteed with 3 V and 5 V supply rails. switching speed, low on resistance, and low leakage currents.
