74HCT4051D,74HCT4052D
1. Functional Description
74HCT4051D:8-Channel Analog Multiplexer/Demultiplexer
74HCT4052D:Dual 4-Channel Analog Multiplexer/Demultiplexer
2. General
The 74HCT4051D/74HCT4052D are high speed CMOS ANALOG MULTIPLEXER/DEMULTIPLEXER
fabricated with silicon gate C
2
MOS technology. They achieve the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. This inputs
are compatible with TTL, NMOS and CMOS output voltage levels.
The 74HCT4051D has an 8 channel configuration and the 74HCT4052D has a 4 channel
×
2 configuration.
The digital signal to the control terminal turns "ON" the corresponding switch of each channel a large amplitude
signal (V
CC
- V
EE
) can then be switched by the small logical amplitude (V
CC
- GND) control signal.
For example, in the case of V
CC
= 5 V, GND = 0 V, V
EE
= -5 V, signals between -5 V and +5 V can be switched
from the logical circuit with a single power supply of 5 V. As the ON-resistance of each switch is low, they can be
connected to circuits with low input impedance.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report
and estimated failure rate, etc).
