TC7MZ4053FK Triple 2-Channel Analog
Multiplexer/Demultiplexer
The TC7MZ4051/4052/4053FK 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 TC7MZ4051/4052/4053FK offer analog/digital signal
selection as well as mixed signals. The 4051 has an 8-channel
configuration, the 4052 has an 4-channel 脳 2 configuration, and
Weight: 0.02 g (typ.)
the 4053 has a 2-channel 脳 3 configuration.
The switches for each channel are turned ON by the control pin
digital signals.
Although the control signal logical amplitude (V
CC
鈭?/div>
GND) is small, the device can perform large-amplitude
(V
CC
鈭?/div>
V
EE
) signal switching.
For example, if V
CC
= 3 V, GND = 0 V, and V
EE
=
鈭?
V, signals between
鈭?
V and +3 V can be switched from the
logical circuit using a single 3 V power supply.
All input pins 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 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
TC7MZ4051/4052/4053FK can be used in a variety of applications, including in the system which has two power
supplies, and in battery backup circuits.
