TTL-Compatible, CMOS Analog Switches
Features
The DG300A through DG303A family of monolithic CMOS
switches are truly compatible second source of the original
manufacturer. The switches are latch-proof and are
• Low Power Consumption
• Break-Before-Make Switching

low leakage and low power consumption, these switches are
ideally suited for precision application in instrumentation,
communication, data acquisition and battery powered
applications. Other key features include Break-Before-Make
switching, TTL and CMOS compatibility, and low ON
resistance. Single supply operation (for positive switch
voltages) is possible by connecting V- to 0V.
