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: t OFF < 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.
