High-Speed CMOS Logic
Analog Multiplexers/Demultiplexers with Latch
Features
CMOS technology to achieve operating speeds similar to
LSTTL with the low power consumption of standard CMOS
integrated circuits.
• Wide Analog Input Voltage Range . . . . . . . . . ±5V (Max)
• Low “On” Resistance
- VCC - VEE = 4.5V. . . . . . . . . . . . . . . . . . . . . . 70Ω (Typ)
- VCC - VEE = 9V . . . . . . . . . . . . . . . . . . . . . . . 40Ω (Typ)
These analog multiplexers/demultiplexers are, in essence,
the HC/HCT4015 and HC4052 preceded by address latches
that are controlled by an active low Latch Enable input (LE).
Two Enable inputs, one active low (E1), and the other active
high (E2) are provided allowing enabling with either input
voltage level.
• Low Crosstalk Between Switches
• Fast Switching and Propagation Speeds
• “Break-Before-Make” Switching
Ordering Information
• Wide Operating Temperature Range . . . -55oC to 125oC
• HC Types
- 2V to 6V Operation, Control; 0V to 10V Switch
- High Noise Immunity: NIL = 30%, NIH = 30% of VCC
at VCC = 5V

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
3. In certain applications, the external load-resistor current may include both VCC and signal-line components. To avoid drawing VCC current
when switch current flows into the transmission gate inputs, the voltage drop across the bidirectional switch must not exceed 0.6V (calculated from RON values shown in the DC Electrical Specifications table). No VCC current will flow through RL if the switch current flows
into terminal 3 on the ’HC4351 and CD74HCT4351; terminals 3 and 13 on the CD74HC4352.
4. The package thermal impedance is calculated in accordance with JESD 51-7.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
