DG5143 Low-Power, High-Speed CMOS Analog Switch Features Benefits Applications 15-V Input Range On-Resistance: 50 Fast Switching Action—tON: 100 ns Low Power—PD: <350 W TTL and CMOS Compatible Improved Signal Headroom Low Signal Errors Break-Before-Make Switching Action Reduced Power Consumption Simple Interfacing Audio Switching Precision Switching High-Speed Switching Battery Powered Systems Description The DG5143 solid state analog switch is built on the Siliconix proprietary high-voltage silicon gate process to achieve high voltage rating and superior switch time on/off performance. Break-before-make switching action guarantees that an on-channel will be turned off before the off-channel can turn on. The DG5143 features ultra-low power supply requirements and TTL and CMOS compatibility. Each switch conducts equally well in both directions when on and blocks input voltages to the supply values when off. This switch is ideal for battery powered industrial applications with a maximum power supply current of 1 A. An expitaxial layer prevents latchup.
