Copyright © Harris Corporation 1999 1 Semiconductor DG181 thru DG191 High-Speed Drivers with JFET Switch Description The DG181 thru DG191 series of analog gates consist of 2 or 4 N-channel junction-type field-effect transistors (JFET) designed to function as electronic switches. Level-shifting drivers enable low-level inputs (0.8V to 2V) to control the ON-OFF state of each switch. The driver is designed to provide a turn-off speed which is faster than turn-on speed, so that break-before-make action is achieved when switching from one channel to another. In the ON state, each switch conducts current equally well in both directions. In the OFF condition, the switches will block voltages up to 20V peak-to-peak. Switch-OFF input-output isolation 50dB at 10MHz, due to the low output impedance of the FET-gate driving circuit. Features • Constant ON-Resistance for Signals to ±10V (DG182, DG185, DG188, DG191), to ±7.5V (All Devices) • ±15V Power Supplies • <2nA Leakage from Signal Channel in Both ON and OFF States • TTL, DTL, RTL Direct Drive Compatibility •tON, tOFF <150ns, Break-Before-Make Action • Cross-Talk and Open Switch Isolation >50dB at 10MHz (75 Ω Load) April 1999 Functional Diagrams (Typical Channel) DG186, DG187, DG188 - ONE AND TWO CHANNEL SPDT AND SPST CIRCUIT CONFIGURATION DG183, DG184, DG185 - TWO CHANNEL DPST CIRCUIT CONFIGURATION S2 D2 S1 D1 V+ GND VL IN V- S D S D V+ GND VL IN V- File Number 3114.4 OBSOLETE PRODUCT POSSIBLE SUBSTITUTE PRODUCT DG184, DG185: HI-5049, HI-5045 DG190: DG403, HI-5051, IH5151 DG191: HI-5043, HI-0390, IH5043 |
