GENERAL DESCRIPTION
The 74HC/HCT4052 are high-speed Si-gate CMOS
devices and are pin compatible with the “4052” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4052 are dual 4-channel analog
multiplexers/demultiplexers with common select logic.
Each multiplexer has four independent inputs/outputs (nY0
to nY3) and a common input/output (nZ). The common
channel select logics include two digital select inputs (S0
and S1) and an active LOW enable input (E).
With E LOW, one of the four switches is selected (low
impedance ON-state) by S0 and S1. With E HIGH, all
switches are in the high impedance OFF-state,
independent of S0 and S1.
VCC and GND are the supply voltage pins for the digital
control inputs (S0 and S1, and E). The VCC to GND ranges
are 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT. The
analog inputs/outputs (nY0 to nY3, and nZ) can swing
between VCC as a positive limit and VEE as a negative limit.
VCC VEE may not exceed 10.0 V.
For operation as a digital multiplexer/demultiplexer, VEE is
connected to GND (typically ground).
QUICK REFERENCE DATA
VEE = GND = 0 V; Tamb =25 °C; tr =tf = 6 ns
Notes
1. CPD is used to determine the dynamic power dissipation (PD in W):
PD =CPD × VCC2 × fi +∑ {(CL + CS) × VCC2 × fo)} where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ {(CL +CS) × VCC2 × fo)} = sum of outputs
CL = output load capacitance in pF
CS = max. switch capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC 1.5 V
