The DG419LDY+ is a precision SPDT CMOS analogue switch in 8 pin NSOIC package. This switch is +3V logic compatible when powered from ±15V or ±12V supplies. It conducts equally well in either direction and has low charge injection of 2.5pC with single +12V supply and low power consumption. The DG419L offers low off leakage current over temperature (less than 5nA at +85°C) and has power supply sequencing free operation. Switching times are less than 175ns for tON and less than 185ns for tOFF. The digital input has a +0.8V logic low threshold and +2V logic high threshold ensuring +3V TTL and CMOS logic compatibility. The device is used in sample and hold circuits, test equipments, guidance and control systems, battery operated systems, military radios, PBX and PABX systems.
