General Description
These devices are a monolithic combination of bipolar and
JFET technology producing the industry’s first one chip
quad JFET switch. A unique circuit technique is employed to
maintain a constant resistance over the analog voltage
range of
g
10V. The input is designed to operate from mini-
mum TTL levels, and switch operation also ensures a break-
before-make action.
These devices operate from
g
15V supplies and swing a
g
10V analog signal. The JFET switches are designed for
applications where a dc to medium frequency analog signal
needs to be controlled.
Features

Low leakage in ‘‘OFF’’ state
Y
TTL, DTL, RTL compatibility
Y
Single disable pin opens all switches in package on
LF11331, LF11332, LF11333
Y
LF11201 is pin compatible with DG201
