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. A unique 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, and switch operation also ensures a
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.
Features
n Analog signals are not loaded
n Constant “ON” resistance for signals up to ±10V and
100 kHz
n Pin compatible with CMOS switches with the advantage
of blow out free handling
n Small signal analog signals to 50 MHz
n Break-before-make action: tOFF < tON
n High open switch isolation at 1.0 MHz: −50 dB
n Low leakage in “OFF” state: <1.0 nA
n TTL, DTL, RTL compatibility
n Single disable pin opens all switches in package on
LF11331, LF11332, LF11333
n LF11201 is pin compatible with DG201
