                                                                                                 SOP-16

     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                            DIP-16
feature low ON impedance and very low OFF leakage current.
Control of analog signals up to the complete supply voltage range
can be achieved.

Note 1. Data of “TYP” is intended as an indication of the IC’s potential performance.
      2. For voltage drops across the switch(∆Vsw)>600mV (>300mV at high temperature), excessive VDD current
         may be drawn, i.e. the current out of the switch may contain both VDD and switch input components. The
         reliability of the device will be unaffected unless the Maximum Ratings are exceeded.

  • 1. UNISONIC TECHNOLOGIES CO., LTD 4051 CMOS IC 8-CHANNEL ANALOG MULTIPLEXERS/DEMULTIPLEXERS SOP-16 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 DIP-16 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 TSSOP-16 * Wide Analog Voltage Range: VDD–VEE = 3V~18V. (Note: VEE must be≦VSS) *Pb-free plating product number: 4051L * Break-Before-Make Switching Eliminates Channel Overlap. * Linearized Transfer Characteristics * Implement an SP8T solid state switch effectively. * Pin–to–Pin Replacement for CD4051 ORDERING INFORMATION Order Number Package Packing Normal Lead Free Plating 4051-S16-R 4051L-S16-R SOP-16 Tape Reel 4051-S16-T 4051L-S16-T SOP-16 Tube 4051-P16-R 4051L-P16-R TSSOP-16 Tape Reel 4051-P16-T 4051L-P16-T TSSOP-16 Tube 4051-D16-T 4051L-D16-T DIP-16 Tube www.unisonic.com.tw 1 of 6 Copyright © 2005 Unisonic Technologies Co., LTD QW-R502-054,A
