Logic - Gates and Inverters

The NL27WZ32USG is a single-pole double-throw (SPDT) analog switch IC, ideal for use in switching applications which require excellent signal integrity.This switch IC is capable of handling a voltage range from -15V to +15V, and is designed to have very low input leakage current of 10pA at 25°C and a noise-induced on-resistance (ron) of 200Ω in the low frequency range. The NL27WZ 32USG is also designed to be radiation immune, making them ideal for use in space applications where radiation is known to cause signal degradation.

Application field

The NL27WZ32USG is typically used in applications that require low voltage, low power, and low leakage current. These features make it an ideal choice for many switching applications, including signal routing, multiplexers, sample and hold circuits, and analog signal sources.

The NL27WZ32USG has also found application in data acquisition and signal isolation. Due to its low power consumption and low noise characteristics, the NL27WZ32USG is often used in \'noise-rejecting\' applications. These include video and video distribution amplifiers, radio, remote control receivers, power line modems and medical imaging equipment.

Working principle

The NL27WZ32USG is a single-pole, double Throw (SPDT) switch which is composed of two p-Channel MOSFETs connected in series. The two MOSFETs are connected to a common gate terminal which is used for controlling the switch.

The NL27WZ32USG operates by controlling the voltage applied to the gate terminals of the two MOSFETs. When the gate terminal is driven high, the corresponding p-Channel MOSFET is turned on and current is allowed to flow through the device. When the voltage applied to the gate terminal is driven low, the corresponding p-Channel MOSFET is turned off and current is prevented from flowing. By using this principle, the NL27WZ32USG is able to switch between two different voltage levels.

The NL27WZ32USG is an extremely fast switch, having an input gate capacitance of 4pF and a switching time of 50ns (L-H) or 15ns (H-L). This makes the NL27 WZ32 USG suitable for high-speed switching applications. The NL27WZ32USG is also designed for low power consumption, making it well suited for applications that require power conservation.
