Logic—Specialty Logic includes many components intended for specific applications including the SN74LVTH18502APM. In this article, we’ll take a look at the application field and working principle of this device.

SN74LVTH18502APM Overview

The SN74LVTH18502APM is a dual-supply voltage LVT (Low Voltage Transistor) device that has an input range of 0 to Vcc-1.5V. It can operate up to 18V and is designed for low-voltage, high-speed applications. The SN74LVTH18502APM has an open drain output which can toggle between high and low logic states. It also has an integrated pull-up element for use in applications with weak pull-up circuitry. Additionally, it features low-leakage current characteristics with a low static power consumption.

Application Field

The SN74LVTH18502APM has a number of applications such as being used as a level shifter and in pull-up current control logic applications. It is commonly used in battery-powered interfaces and has a wide range of applications, including automotive, consumer electronics, and industrial applications. Additionally, it is used as a clock buffer, register, gate and latch in multiplexers, decoders and logical integrated circuits.

Working Principle

The SN74LVTH18502APM is designed to operate from either a positive or negative voltage source. When powered from a positive voltage source, the SN74LVTH18502APM is essentially a voltage-controlled switch. When a positive voltage is applied to the input, the device will enable the integrated pull-up element and the output will transition to a high logic state. When a zero voltage is applied to the input, the device will disable the pull-up element and the output will transition to a low logic state. When powered from a negative voltage source, the SN74LVTH18502APM essentially functions as a current mirror, with the input current being mirrored and output with the same level of current. The device is an ideal choice for level shifting applications due to the integrated pull-up element.

Conclusion

The SN74LVTH18502APM is a versatile low-voltage, high-speed device from the Logic – Specialty Logic family. It is designed for use in a variety of applications, including level shifting, pull-up current control logic, and multiplexers, decoders and logical integrated circuits. It is ideal for use in low-power, battery-powered interfaces and other low-voltage applications. The integrated pull-up element makes the device suitable for weak pull-up signals and its low static power consumption makes it highly efficient.
