Quad SPST JFET Analog Switches

General Description

Features

n Analog signals are not loaded

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

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: t_OFFt_ON

n High open switch isolation at 1.0 MHz: −50 dB

n Low leakage in “OFF” state:

n TTL, DTL, RTL compatibility

n Single disable pin opens all switches in package on

LF11331, LF11332, LF11333

10V. The input is designed to operate from minimum TTL

levels, and switch operation also ensures

break-before-make action.

These devices operate from 15V supplies and swing a

10V analog signal. The JFET switches are designed for ap-

1.0 nA

plications where a dc to medium frequency analog signal

needs to be controlled.

n LF11201 is pin compatible with DG201
