The 74LCX543MTC is a high-performance non-inverting transceiver from Fairchild Semiconductor, part of the 74LCX logic family. It operates from 2V to 3.6V, providing 24mA sink and source capability. This single-channel device features 3-State outputs for bus-oriented applications. Its low-voltage operation makes it suitable for battery-powered and portable electronics, as well as general-purpose data buffering and level shifting between 2.5V and 3.3V systems. The 24-TSSOP package offers a compact footprint for space-constrained designs.
- Low-Voltage Operation (2V-3.6V): Reduces power consumption and enables compatibility with modern low-voltage processors and FPGAs.
- High Drive Current (24mA): Ensures robust signal integrity even with heavy capacitive loads on the bus.
- 3-State Outputs: Allows multiple devices to share a common bus without contention, simplifying system design.
- Non-Inverting Logic: Preserves signal polarity, reducing design complexity and potential errors.
Bus Interfacing for Mixed-Voltage Systems
With a 2V to 3.6V supply range, the 74LCX543MTC can interface between 2.5V and 3.3V logic domains, ensuring reliable data transfer in mixed-voltage environments.
Bidirectional Data Buffering
As a non-inverting transceiver, it buffers data between two buses, preventing signal degradation and improving drive strength for longer traces.
Memory Address/Data Latching
The 3-State outputs allow the device to be used in memory systems where multiple devices share a common data bus, providing high-impedance states when not selected.
Level Shifting in Portable Electronics
Ideal for battery-powered devices, the low-voltage operation reduces power consumption while shifting signals between different voltage sections of a PCB.
Industrial Sensor Interfaces
In industrial controls, this transceiver can buffer sensor signals to a controller, providing clean, isolated data paths with 24mA output drive.
Telecom Line Cards
Used in telecom equipment for buffering control and data signals between backplane and line interface modules, ensuring signal integrity over connectors.
