CMOS IC
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: VDD–VEE = 3V~18V.
(Note: VEE must be≦VSS)
* Break-Before-Make Switching Eliminates Channel Overlap.
* Linearized Transfer Characteristics
* Implement an SP8T solid state switch effectively.
* Pin–to–Pin Replacement for CD4051

Notes: 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.
