The TC74LCX541FK(EL,K) is a 5.5V Low-Power CMOS Logic-Buffers, Drivers, Receivers, Transceivers, that operates in both 3V and 5V single power supply. Different than the traditional logic level translation, the LCX541FK doesn’t require any changes in circuit timing and power supply. Combining a low power consumption rate with a high-speed operation, the TC74LCX541FK is a perfect choice for applications that require small power and quick response.

The two PEVS output potentials, the VCC and ground potentials, are generated by differences in the input logic levels. This means that the LCX541FK can be used as a digital logic function generator, and an analog output, to drive devices from 5V lines. Additionally, the output buffer devices can be configured as a driver, for relays, motor drivers, and other CMOS devices, offering a wide variety of functions.

The TC74LCX541FK features a 5V tolerant input, allowing for direct connection to five-volt logic devices, making it an ideal choice for devices that accept a +5V TTL level. It can also be used as a bi-directional driver, offering resistance between logic inputs and output pins. The adjustment and protection components, including a diode, help protect the input and output and provide maximum flexibility.

The high-speed level shifter design of the TC74LCX541FK employs a combination of a Schmitt trigger and a logic input stage, which operate in tandem to provide an enhanced low voltage logic stage. This two-stage logic level shifter allows the outputs to operate in either 3V or 5V levels, depending on the input logic state.

The TC74LCX541FK operates over a wide range of voltages, from 1.5V to 5.5V, making it an ideal choice for applications that need to operate from a single supply. The supply voltage ranges from 1.6V to 5.5V, with a maximum input voltage of 5.5V. The complete logic level range is from 0.5V to 5.5V.

The other main features of the TC74LCX541FK include its high-speed level shifting and its thermal shutdown protection. The input level of the TC74LCX541FK can be set to either 3V to 5V or 0.5V to 5V, depending on the application. The thermal shutdown protection monitors the internal temperature of the IC and shuts off the power supply if its temperature rises to an unacceptable level.

In summary, the TC74LCX541FK is a 5.5V low-power CMOS logic-level shifter that can be used as either a single level buffer or a bi-directional driver. It enables circuit timing and power supply changes to be minimized while providing a fast, low-power logic level converter. The device offers high-speed level shifting, 5V tolerant inputs, and thermal shutdown protection, making it suitable for a variety of applications.
