CMOS Digital Integrated Circuits Silicon Monolithic
74VHC4051AFT,74VHC4052AFT,74VHC4053AFT
1. Functional Description
74VHC4051AFT:8-Channel Analog Multiplexer/Demultiplexer
74VHC4052AFT:Dual 4-Channel Analog Multiplexer/Demultiplexer
74VHC4053AFT:Triple 2-Channel Analog Multiplexer/Demultiplexer
2. General
The 74VHC4051AFT, 74VHC4052AFT and 74VHC4053AFT are high-speed, low-voltage drive analog
multiplexer/demultiplexers using silicon gate CMOS technology. In 3 V and 5 V systems these can achieve high-
speed operation with the low power dissipation that is a feature of CMOS.
The 74VHC4051AFT, 74VHC4052AFT and 74VHC4053AFT offer analog/digital signal selection as well as mixed
signals. The 74VHC4051AFT has an 8-channel configuration, the 74VHC4052AFT has an 4-channel
×2
configuration, and the 74VHC4053AFT has a 2-channel
×3
configuration.
The switches for each channel are turned ON by the control pin digital signals.
All control inputs are equipped with a newly developed input protection circuit that avoids the need for a diode
on the plus side (forward side from the input to the V
CC
). As a result, for example, 5.5 V signals can be permitted
on the inputs even when the power supply voltage to the circuits is off. As a result of this input power protection,
the 74VHC4051AFT, 74VHC4052AFT and 74VHC4053AFT can be used in a variety of applications, including
in the system which has two power supplies, and in battery backup circuits.

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).
