Dual 4-channel Analog Multiplexer/Demultiplexer
AZ4052
General Description
The AZ4052 is high-speed si-gate CMOS device. The
AZ4052 is dual 4-channel analog multiplexers or
demultiplexers with common select logic. Each
multiplexer has four independent inputs/outputs (pins
nY0 to nY3) and a common input/output (pin nZ).
The common channel select logics include two digital
select inputs (pins S0 and S1) and an active LOW
___
___
enable input (pin E). When pin E=LOW, one of the
four switches is selected (Low-impedance On-state)
___
with pins S0 and S1. When pin E =HIGH, all
switches are in the high-impedance Off-state,
independent of pins S0 and S1. V_CC and GND are the
supply voltage pins for the digital control inputs (pins
___
S0, S1 and E). The V_CC to GND ranges are 3.0V to
10V. The analog inputs/outputs (pins nY0 to nY3 and
nZ) can swing between V_CC as a positive limit and
V_EE as a negative limit. V_CC-V_EE may not exceed 10V.
For operation as a digital multiplexer/demultiplexer,
V_EE is connected to GND (Typically Ground).
The AZ4052 is available in standard packages of
SOIC-16 and DIP-16.
