TC74LVX4053F/FT/FK Triple 2-Channel Analog Multiplexer/Demultiplexer TC74LVX4051F, TC74LVX4052F, TC74LVX4053F The TC74LVX4051/4052/4053 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 TC74LVX4051/4052/4053 offer analog/digital signal selection as well as mixed signals. The 4051 has an 8-channel configuration, the 4052 has an 4-channel × 2 configuration, and the 4053 has a 2-channel × 3 configuration.
The switches for each channel are turned ON by the control pin digital signals.
Although the control signal logical amplitude (VCC − GND) is small, the device can perform large-amplitude (VCC − VEE) signal switching.
For example, if VCC = 3 V, GND = 0 V, and VEE = −3 V, signals between −3 V and +3 V can be switched from the logical circuit using a single 3 V power supply.
All control 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 VCC). 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 TC74LVX4051/4052/4053 can be used in a variety of applications, including in the system which has two power supplies, and in battery backup circuits.
