The 74LCXH245MTCX is a single-channel (8-bit) non-inverting transceiver from Fairchild's 74LCXH family. It operates from 2V to 3.6V, with an impressive 24mA source/sink current per channel. The 3-State outputs and bidirectional capability make it ideal for high-speed bus applications. Packaged in a 20-TSSOP, it is designed for servers, telecom, and industrial systems requiring high drive strength.
- High Output Current (24mA): Drives capacitive loads and long traces effectively.
- Low-Voltage Operation (2V-3.6V): Reduces power in 3.3V systems.
- Bidirectional Transceiver: Simplifies data bus design.
- 3-State Outputs: Enables bus sharing without contention.
High-Current Bus Transceiver
Drive long data buses with high capacitance using the 24mA output capability, ensuring signal integrity over extended traces.
3.3V Backplane Interfacing
In networking equipment, this transceiver connects line cards to backplanes, handling high-speed data with low noise.
Memory Module Buffering
Buffer data lines between a memory controller and DDR modules, where high drive strength is required.
