NTE861

NTE861 Integrated Circuit Quad, Normally Open, SPST JFET Analog Switch w/Disable Description: The NTE861 is a monolithic combination of bipolar and JFET technology producing a one chip quad JFET switch. A unique circuit technique is employed to maintain a constant resistance over the analog voltage range of ±10V. The input is designed to operate from minimum TTL levels, and switch operation also ensures a break–before–make action. Features: D Analog signals are not loaded D Constant “ON” resistance for signals up to ±10V and 100kHz D Pin compatible with CMOS switches with the advantage of blow out free handling D Small signal analog signals to 50MHz D Break–before–make action D High open switch isolation at 1.0MHz D Low leakage in “OFF” state D TTL, DTL, RTL compatibility D Single disable pin opens all switches in package This device operates from a ±15V supply and swings a ±10V analog signal. The JFET switches are designed for applications where a dc to medium frequency analog signal needs to be controlled.
