U74LVX4052

UNISONIC TECHNOLOGIES CO., LTD U74LVX4052 Dual 4-Channel Analog Multiplexer/Demultiplexer CMOS IC  DESCRIPTION The U74LVX4052 is a high speed, low-voltage drive analog multiplexer/demultiplexer using silicon gate CMOS technology. In 3V and 5V systems these can achieve high-speed operation with the low power dissipation that is a feature of CMOS. The U74LVX4052 offer analog/digital signal selection as well as mixed signals wish a 4-Channel×2 configuration. The switchses 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=3V, GND=0V and VEE=-3V, signals between -3V and +3V can be switched from the logical circuit using a signal 3V 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 (forword side from the input to the VCC).As a result, for example, 5V 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 U74LVX4052 can be used in a variety of applications, including in the system which has two power supplies, and in battery bachup circuits.  FEATURES * Low ON resistance: RON=22Ω(Typ.)(VCC-VEE=3V) * RON=15Ω(Typ.)(VCC-VEE=6V) * High Speed: tpd=3ns (Typ.)(VCC=3V) * Low power Dissipation: ICC=4μA (Max.)(TA=25°C) * Input level: VIL=0.8...
