GENERAL DESCRIPTIONThe 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
multiplexer has two independent inputs/outputs (nY0 and
nY1), a common input/output (nZ) and select inputs (S1to
S3).
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).
WithE1 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). WhenLE is HIGH, the
latch is transparent. When either of the two enable inputs, (active LOW) and E2 (active HIGH), is inactive, all
analog switches are turned off.
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.
For operation as a digital multiplexer/demultiplexer, VEEis
connected to GND (typically ground).
QUICK REFERENCE DATAVEE= GND = 0 V; Tamb = 25 °C;tr = tf = 6 ns
Notes CPD is used to determine the dynamic power
dissipation (PDin μW):=
CPD× VCC2×fi+∑ {(CL +CS)× VCC2×fo} where: = input frequency in MHz= output load capacitance in pF = output frequency in MHz {(CL ×CS)× VCC2×fo} = sum of outputs
VCC= supply voltage in V For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC− 1.5 V

RATINGSLimiting values in accordance with the Absolute Maximum System (IEC 134)
Voltages are referenced to VEE= GND (ground = 0 V)
Note to ratings 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.

DC CHARACTERISTICS FOR 74HC/HCTFor 74HC: VCC− GND or VCC− VEE = 2.0, 4.5, 6.0 and 9.0 V
For 74HCT: VCC− GND = 4.5 and 5.5 V; VCC− VEE = 2.0, 4.5, 6.0 and 9.0 V
Notes to DC characteristics 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.
