Quad SPST JFET Analog Switches
General Description
These devices are a monolithic combination of bipolar and
JFET technology producing the industry’s first one chip quad
JFET switch.Aunique circuit technique is employed to main-
tain a constant resistance over the analog voltage range of
±
10V. The input is designed to operate from minimum TTL
levels,

break-before-make action.
These devices operate from
±
15V supplies and swing a
±
10V analog signal. The JFET switches are designed for ap-
plications where a dc to medium frequency analog signal
needs to be controlled.
