The TC74VHC4051A/4052A/4053A 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 TC74VHC4051A/4052A/4053A offer analog/digital signal
selection as well as mixed signals. The 4051A has an 8-channel
configuration, the 4052A has an 4-channel × 2 configuration, and
the 4053A 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 TC74VHC4051A/4052A/4053A can be used
in a variety of applications, including in the system which has
two power supplies, and in battery backup circuits.
