LF11331 Datasheet | National Semiconductor

Description These devices are a monolithic bination of bipolar and JFET technology producing the industry’s first one chip quad JFET switch. 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 k Hz n Pin patible 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 < t ON n High open switch isolation at 1.0 MHz: - 50 d B n Low leakage in “OFF” state: < 1.0 n A n TTL, DTL, RTL patibility n Single disable pin opens all switches in package on LF11331, LF11332, LF11333 n LF11201 is pin patible with DG201 Test Circuit and Schematic Diagram DS005667-2 FIGURE 1.
