The MC74LCX245 is a high-performance octal bus transceiver from onsemi, designed for bidirectional asynchronous communication. Operating from 2V to 5.5V, it supports mixed-voltage systems and delivers 24mA output current. Its 3-State outputs allow bus sharing, while the non-inverting function preserves signal integrity. Housed in a compact 20-TSSOP package, it is ideal for telecom, computing, and industrial applications requiring reliable data transfer.
- Wide 2V to 5.5V Supply Range: Compatible with 3.3V and 5V logic, simplifying mixed-voltage design.
- High 24mA Output Current: Drives heavy loads and long traces, ensuring signal integrity.
- 3-State Outputs: Enables bus multiplexing without contention, improving system flexibility.
- Extended Temperature Range (-55°C to 125°C): Suitable for harsh automotive and industrial environments.
Bidirectional Bus Interfacing
Use the MC74LCX245 to connect a 3.3V microcontroller to a 5V peripheral bus. The 3-State outputs and non-inverting design ensure clean data transfer without signal inversion.
Signal Buffering for High-Speed Data Lines
With a 2V to 5.5V supply range and 24mA output current, this transceiver buffers high-speed signals in networking equipment, reducing signal degradation over long PCB traces.
Level Shifting in Mixed-Voltage Systems
In systems with both 3.3V and 5V logic, the 74LCX family's wide voltage range allows direct interfacing, simplifying design and eliminating the need for external level shifters.
Driving Multiple Loads in Industrial Controls
The 24mA sink/source capability enables driving multiple TTL loads in industrial PLCs and control systems, ensuring reliable logic levels even with high fan-out.
Memory Address/Data Bus Expansion
Use it to buffer address and data lines between a CPU and memory modules. The 3-State outputs allow multiple devices to share the bus without interference.
Automotive ECU Communication
With a temperature range of -55°C to 125°C, it is suitable for automotive ECUs, buffering CAN or LIN signals between the controller and transceiver.
