HEF4052B
MSI
Dual 4-channel analogue multiplexer/demultiplexer
Both multiplexers/demultiplexers
contain four bidirectional analogue
switches, each with one side
connected to an independent
input/output (Y0 to Y3) and the other
side connected to a common
input/output (Z).
VDD and VSS are the supply voltage
connections for the digital control
inputs (A0, A1 and E). The VDD to
VSS range is 3 to 15 V. The analogue
inputs/outputs (Y0 to Y3, and Z) can
swing between VDD as a positive limit
and VEE as a negative limit.
DESCRIPTION
The HEF4052B is a dual 4-channel
analogue multiplexer/demultiplexer
with common channel select logic.
Each multiplexer/demultiplexer has
four independent inputs/outputs
(Y0 to Y3) and a common input/output
(Z). The common channel select logic
includes two address inputs (A0 and
A1) and an active LOW enable input
(E).
VDD − VEE may not exceed 15 V.
With E LOW, one of the four switches
is selected (low impedance ON-state)
by A0 and A1. With E HIGH, all
switches are in the high impedance
OFF-state, independent of A0 and A1.
For operation as a digital
multiplexer/demultiplexer, VEE is
connected to VSS (typically ground).
