三组二选一模拟开关CD4053BC


Description
The CD4051BC, CD4052BC, and CD4053BC analog mul-
tiplexers/demultiplexers are digitally controlled analog
switches having low “ON” impedance and very low “OFF”
leakage currents. Control of analog signals up to 15Vp-p
can be achieved by digital signal amplitudes of 3−15V. For
example, if VDD
= 5V, VSS
= 0V and VEE
= −5V, analog sig-
nals from −5V to +5V can be controlled by digital inputs of
0−5V. The multiplexer circuits dissipate extremely low qui-
escent power over the full VDD−VSS and VDD−VEE supply
voltage ranges, independent of the logic state of the control
signals. When a logical “1” is present at the inhibit input ter-
minal all channels are “OFF”.
CD4053BC is a triple 2-channel multiplexer having three
separate digital control inputs, A, B, and C, and an inhibit
input. Each control input selects one of a pair of channels
which are connected in a single-pole double-throw configu-
ration.

Features
Wide range of digital and analog signal levels:digital 3 – 15V, analog to 15Vp-p
Low “ON” resistance: 80Ω (typ.) over entire 15Vp-p signal-input range for VDD-VEE = 15V
High “OFF” resistance:channel leakage of ±10 pA (typ.) at VDD − VEE = 10V
Logic level conversion for digital addressing signals of 3 – 15V (VDD− VSS = 3 – 15V) to switch analog signals to
15 Vp-p (VDD − VEE = 15V)
Matched switch characteristics:∆RON = 5Ω (typ.) for VDD − VEE = 15V
Very low quiescent power dissipation under all digital-control input and supply conditions:
1 µ W (typ.) at VDD − VSS= VDD− VEE = 10V
