Triple 2-channel analog
multiplexer/demultiplexer with latch
74HC/HCT4353
multiplexer has two independent inputs/outputs (nY0 and
nY1), a common input/output (nZ) and select inputs (S1 to
S3).
FEATURES
• Wide analog input voltage range: ± 5 V
• Low “ON” resistance:
80 Ω (typ.) at VCC − VEE = 4.5 V
70 Ω (typ.) at VCC − VEE = 6.0 V
60 Ω (typ.) at VCC − VEE = 9.0 V
Each multiplexer/demultiplexer contains two bidirectional
analog switches, each with one side connected to an
independent input/output (nY0 and nY1) and the other side
connected to a common input/output (nZ).
• Logic level translation:
to enable 5 V logic to communicate with ± 5 V analog
signals
With E1 LOW and E2 HIGH, one of the two switches is
selected (low impedance ON-state) by S1 to S3.
The data at the select inputs may be latched by using the
active LOW latch enable input (LE). When LE is HIGH, the
latch is transparent. When either of the two enable inputs,
E1 (active LOW) and E2 (active HIGH), is inactive, all
analog switches are turned off.
• Typical “break before make” built in
• Address latches provided
• Output capability: non-standard
• ICC category: MSI
VCC and GND are the supply voltage pins for the digital
control inputs (S1 to S3, LE, E1 and E2). 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 and nY1, and nZ) can
swing between VCC as a positive limit and VEE as a
negative limit. VCC − VEE may not exceed 10.0 V.
GENERAL DESCRIPTION
The 74HC/HCT4353 are high-speed Si-gate CMOS
devices. They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT4353 are triple 2-channel analog
multiplexers/demultiplexers with two common enable
inputs (E1 and E2) and a latch enable input (LE). Each
For operation as a digital multiplexer/demultiplexer, VEE is
connected to GND (typically ground).

Notes
∑ {(CL ×CS) × VCC2 × fo} = sum of outputs
1. CPD is used to determine the dynamic power
dissipation (PD in µW):
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
PD =
CPD × VCC2 × fi + ∑ {(CL + CS) × VCC2 × fo} where:
fi = input frequency in MHz
ORDERING INFORMATION
CL = output load capacitance in pF
See “74HC/HCT/HCU/HCMOS Logic Package
Information”.
fo = output frequency in MHz

Note to ratings
1. To avoid drawing VCC current out of terminals nZ, when switch current flows in terminals nYn, the voltage drop across
the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminals nZ, no VCC current will flow
out of terminals nYn. In this case there is no limit for the voltage drop across the switch, but the voltages at nYn and
nZ may not exceed VCC or VEE.

Notes to DC characteristics
1. At supply voltages (VCC − VEE) approaching 2.0 V the analog switch ON-resistance becomes extremely non-linear.
There it is recommended that these devices be used to transmit digital signals only, when using these supply
voltages.
2. For test circuit measuring RON see Fig.8.

Notes to the AC characteristics
1. Adjust input voltage Vis to 0 dBm level (0 dBm = 1 mW into 600 Ω).
2. Adjust input voltage Vis to 0 dBm level at Vos for 1 MHz (0 dBm = 1 mW into 50 Ω).
General note
Vis is the input voltage at an nYn or nZ terminal, whichever is assigned as an input.
Vos is the output voltage at an nYn or nZ terminal, whichever is assigned as an output.
Test conditions:
VCC = 4.5 V; GND = 0 V; VEE = − 4.5 V;
RL = 50 Ω; Rsource = 1 kΩ.
