DG300A, DG301A, DG303A
TTL-Compatible, CMOS Analog Switches
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
designed to block signals up to 30VP-P when OFF. Featuring
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.
