1 / 8 page 1 PS8444 01/13/00 Features Low On-Resistance (17 Ohm typ.) Minimizes Distortion and Error Voltages Low Glitching Reduces Step Errors and Improves Settling Times. Charge Injection: <10pC Dual-Supply Operation (±2.7V to ±8V) Single-Supply Operation (+2.7V to +15V) Improved Second Sources for MAX394 On-Resistance Matching Between Channels: <2 Ohm On-Resistance Flatness: 4 Ohm (Max.) Low Off-Channel Leakage, INO(OFF) < 2.5nA @ +85°C TTL/CMOS Logic Compatible (w/ +5V or ±5V supplies) Break-Before-Make action eliminates momentary crosstalk Rail-to-RailAnalog Signal Range Narrow SOIC and QSOP Packages Minimize Board Area Applications Data Acquisition Systems Audio Switching and Routing Test Equipment PBX, PABX Telecommunication Systems Battery-Powered Systems Description The PS394 is a precision, low-voltage, quad, single-pole/double- throw (SPDT) analog switch. The four independent switches oper- atewithbipolarsuppliesrangingfrom±2.7Vto±8V,orwithasingle supply of +2.7V to +15V. The PS394 offers low On-resistance (less than 35 Ohm), guaranteed to match within 2 Ohm between channels and to remain flat over the analog signal range (4 Ohm Max.). It also offers break-before-make switching (10ns typical), with turn-off times less than 75ns and turn-on times less than 130ns. The PS394 is ideal for portable operation since quiescent current runs less than 1µA with all inputs high or low. This monolithic, quad switch is fabricated using Pericoms 17V silicon-gateprocess.Designimprovementsguaranteeextremelylow chargeinjection(10pC),lowpowerconsumption(10µW),andelec- trostatic discharge (ESD) greater than 2000V. Logic Inputs are TTL and CMOS compatible and guaranteed over a+0.8Vto+2.4Vrange.Logicinputsandswitchedanalogsignalscan range anywhere between the supply voltages without damage.
