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.

Features

Analog signals are not loaded

Constant “ON” resistance for signals up to±10V and 100 kHz

Pin compatible with CMOS switches with the advantage of blow out free handling

Small signal analog signals to 50 MHz

Break-before-make action: tOFF High open switch isolation at 1.0 MHz: −50 dB

Low leakage in “OFF” state: <1.0 nA

TTL, DTL, RTL compatibility

Single disable pin opens all switches in package on LF11331, LF11332, LF11333

LF11201 is pin compatible with DG201
