A unique circuit technique is employed to maintain 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 applications 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 Test Circuit and Schematic Diagram DS005667-2 FIGURE 1.
