The NLSX4014DR2G is a logic translator and level shifter, operating on a range of supply voltages (2.3 V to 3.6 V) with a gate delay of 7.9 ns. It is a four-channel device that can drive either two high-side and two low-side switches or four high-side switches. It is ideal for applications that require a range of supply voltages and must be powered from a Vcc of 3.3 V, particularly for mixed low-side and high-side loads.

Application Field

NLSX4014DR2G logic translators are generally used in a variety of embedded systems and automotive applications. Automotive applications may include LED drivers, MOSFET terminals, Gauge meter drivers, HVAC controllers, motor drivers, Lighting ballast drivers, Transconductance Amplifier outputs, or Battery chargers.

It is also used in microcontroller and microprocessor-driven systems for engine controls, instrument clusters, user interface, power supplies, and other similar applications. It is used in ASICs and FPGAs where logic levels must be changed from one voltage to another.

NLSX4014DR2G logic translators can also be used in personal computers, peripherals, power management, medical equipment and test equipment. In portable thin-film transistor (TFT) liquid-crystal displays (LCDs), it is used to switch power sources between 3.3V, 2.5V and 1.8V. It is also used in LCD television and notebook displays, power converters, power supplies, and other applications that require a range of supply voltages.

Working Principle

The NLSX4014DR2G is a TTL compatible logic translator and level shifter that operates on a range of supply voltages from 2.3 to 3.6V with a gate delay of 7.9 ns. It consists of two low-side drivers and two high-side drivers in a single package. The low-side drivers are used to switch on the low-side switches, while the high-side drivers are used to switch on the high-side switches.

The device uses complementary outputs—when one output is ON, the other is OFF. This ensures that the bottom side MOSFETs are activated properly and there is no voltage between the ground and the drain (GND-D) of the power switches. A ground connection is provided to each of the high-side and low-side drivers.

The NLSX4014DR2G logic translators employ BiCMOS process to achieve full-drive capability. The IC has built-in thermal protection and output short-circuit protection and a logic input control signal that can be used to enable or disable the output stage. The input signal is protected from electrostatic discharge (ESD) and other damaging effects by the built-in ESD protection diodes.

Conclusion

The NLSX4014DR2G is a logic translator and level shifter, operating on a range of supply voltages from 2.3 V to 3.6 V with a gate delay of 7.9 ns. It is used in a variety of embedded systems and automotive applications, and in projects where logic levels must be changed from one voltage to another. The device has built-in protection features, such as thermal protection and output short-circuit protection, and is ideal for applications that require a range of supply voltages and must be powered from a Vcc of 3.3 V.
