TC74LVX4051FK
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...
