DG201A_MIL/202_MIL Vishay Siliconix Monolithic Quad SPST CMOS Analog Switches (Obsolete for non-hermetic. Use DG201B/202B as pin-for-pin replacements.) FEATURES D D D D D "15-V Input Range Low Off Leakage—ID(on): 0.1 nA Low On-Resistance—rDS(on): 115 W 44-V Maximum Supply Ratings TTL and CMOS Compatible BENEFITS D Wide Input Range D Low Distortion Switching D Can Be Driven from Comparators or Op Amps Without Limiting Resistors APPLICATIONS D D D D Disk Drives Radar Systems Communications Systems Sample-and-Hold DESCRIPTION The DG201A_MIL and DG202_MIL are quad SPST analog switches designed to provide accurate switching over a wide range of input signals. When combining a low on-resistance and a wide signal range ("15 V) with low charge-transfer these devices are well suited for industrial and military applications. switches will block up to 30 V peak-to-peak and have a 44-V absolute maximum power supply rating. These two devices are differentiated by the type of switch actions (See Truth Table). Built on Vishay Siliconix’ high voltage metal gate process to achieve optimum switch performance, each switch conducts equally well in both directions when on. When off these The DG201A_MIL/202_MIL are available in hermetic packages. For plastic packages, use the DG201B/202B as pin-for-pin replacements.
