DG300A, DG301A, DG303A Data Sheet June 1999 File Number 3119.2 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. Features • Low Power Consumption • Break-Before-Make Switching - tON . . . . . . . . . . [ ... ]
