unisonic technologies co., ltd 4051 cmos ic www.unisonic.com.tw 1 of 7 copyright ? 2007 unisonic technologies co., ltd qw-r502-054.b 8-channel analog multiplexers/demultiplexers ? description utc 4051 is single 8-channel analog multiplexers/demultiplexers for application as digitally?controlled analog switches. the device has three binary control inputs and an inhibit input. it feature low on impedance and very low off leakage current. control of analog signals up to the complete supply voltage range can be achieved. ? features * wide analog voltage range: v dd ?v ee = 3v~18v. (note: v ee must be v ss ) * break-before-make switching eliminates channel overlap. * linearized transfer characteristics * implement an sp8t solid state switch effectively. * pin?to?pin replacement for cd4051 dip-16 sop-16 tssop-16 *pb-free plating product number: 4051l ? ordering information ordering number normal lead free plating package packing 4051-d16-t 4051l-d16-t dip-16 tube 4051-p16-r 4051l-p16-r tssop-16 tape reel 4051-p16-t 4051l-p16-t tssop-16 tube 4051-s16-r 4051l-s16-r sop-16 tape reel 4051-s16-t 4051l-s16-t sop-16 tube 4051l-d16-t (1)packing type (2)package type (3)lead plating (1) r: tape reel, t: tube (2) d16: dip-16, p16: tssop-16, s16: sop-16 (3) l: lead free plating, blank: pb/sn
