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 ana-
log 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.
