Analog SwitchesAM3705/ AM3705C 8-channel MOS analog multiplexergeneral descriptionThe AM3705/AM3705C is an eight-channel MOSanalog multiplex switch. TTL compatible logicinputs that require no level shifting or inputpull·up resistors and operation over a wide rangeof supply voltages is obtained by constructing thedevice with low threshold P·channel enhancementMOS technology. To simplify external logic reoquirements, a one·of·eight decoder and an outputenable are included in the device.Important design features include:• TTL/DTL compatible input logic levels• Operation from standard +5V and -15V suppl ies• Wide analog voltage range - ±5V• One·of·eight decoder on chip• Output enable control• Low ON resistance - 150[2• I nput gate protection• Low leakage currents - 0.5 nAThe AM3705/AM3705C is designed as a low costanalog multiplex switch to fulfill a wide variety ofdata acquisition and data distribution applicationsincluding cross·point switching, MUX front endsfor AID converters, process controllers, automatictest gear, programmable power supplies and othermilitary or industrial instrumentation applications.For information on other National analog switches,see listing on page 162.l>s:w.....oUI.......l>s:w.....oUI(")block diagram (MIL·STD-8068)connection diagramIlATA INPUTCHANNEL NO:SLhhhhhhhoOATA OUTPUTDual·ln·Line PackageDE 1 16 22Vss 2 15 21OUT 3 14 2°V,. 4s, ,13 VDDONE·OUT·OF-EIGHT DECODERS,6VooS. 1S. 8g s,2' 22 OUTPUTENABLElOGIC INPUT'"Both Vsslinesare internallyconnected;eithel one orbothmav bellsed.TOP VIEWtruth tableLOGIC INPUTS20 2' 2'L L LH L LL H LH H LL L HH L HL H HH H HX X XDEHHHHHHHHLCHANNELONS,S,S,S,S,S,S,SaOFFtypical applicationsBuffered a·Channel Multiplex, Sample and HoldWide Input Range Analog SwitchINPUTS"""'1",ANALOGOUTPUTINPUTS"""'1_ANAlOGOUTPUTCHANNELSHECTITTl)A".I.~S'9 ..
