SW-201

The SW-201 has the following features including Highly Realstant to Static Dlacharge Deatruction;Guaranteed Break-Betore-IVtake Switching (toff < ton);Digital Inputs are TTL end CMOS Compadbla;Dual or Single Supply Operation;Avaiiable in Die Form.

The SW-201  consists of four independent,single-pole, single-throw (SPST) analog switches, which may be independently digitally controlled. The judicious combination of bipolar and FET devices in a single monolithic IC results in a product with performance characteristics and ruggedness that are superior to those of a similar circuit fabricated using CMOS technology.Increased reliability is complemented by excellent electrical specifications. Potential error sources of SW-201 are reduced by minimizing "ON" resistance and controlling leakage currents at high temperatures. The switching FET exhibits minimal RpN variation over a 20V analog signal range and with power supply voltage changes. Operation from a single positive power supply voltage is possible. With V+= 36V, V-= OV, the analog signal range will extend from ground to +32V.The PNP logic inputs are TTL and CMOS compatible. Logic input currents are at micro-ampere levelswhich improves circuit fan in.Electrical tests of SW-201 are performed at wafer probe to the limits shown.guaranteed for standard product dice. Consult factory to negotiate.Due to variations in assembly methods end normal yield loss, yield after packaging is not specifications based on dice lot qualification through sample lot assembly and testing.

Thisanalog switch employs ion-implanted JFETs of SW-201 in a switch configuration designed to assure break-before-make action.The turn-off time is much faster than the turn-on time to guarantee this feature over the full operating temperature and input voltage range. Fabricated with Bipolar-JFET processing rather than CMOS, special handling is not necessary to prevent damage to these switches. Because the digital inputs of SW-201 only  require a  2V  logic  "1"  input level,  power-consuming pullup resistors are not required for TTL tom-patibility to insure break-before-make switching as is most often the case with CMOS switches.
