The SN74ALVCH16543DL is a 2-channel non-inverting transceiver from Texas Instruments, part of the 74ALVCH logic family. It operates from 1.65V to 3.6V, enabling seamless interfacing between 1.8V and 3.3V logic domains. Each channel can source or sink 24mA, providing strong drive for bus lines and capacitive loads. The 3-State outputs allow for bidirectional data flow with bus isolation, essential in shared-bus architectures. Packaged in a 56-BSSOP (0.295", 7.50mm Width) package, it is ideal for high-density applications such as servers, telecom equipment, and industrial controls. Its low propagation delay and high-speed operation ensure reliable performance in critical data paths.
- Bidirectional Transceiver Function: Enables data flow in both directions, reducing component count.
- Wide 1.65V to 3.6V Supply Range: Supports mixed-voltage systems without additional level shifters.
- High Drive Current (24mA): Ensures signal integrity over long bus traces.
- 3-State Outputs: Prevents bus contention and allows multiple devices to share the bus.
- Compact 56-BSSOP Package: Ideal for space-constrained, high-pin-count designs.
Bidirectional Data Bus for Microprocessors
Use the SN74ALVCH16543DL to interface a 16-bit microprocessor with a memory or peripheral bus. The transceiver function allows data to flow in both directions, controlled by direction pins, while 3-State outputs prevent bus contention.
Level Shifting in Mixed-Voltage Systems
With a supply range of 1.65V to 3.6V, this transceiver can bridge a 1.8V FPGA to a 3.3V peripheral bus. The non-inverting design preserves data integrity, and the high drive current ensures signal quality.
Server Motherboard Memory Channels
In server platforms, this transceiver buffers address and data lines between the memory controller and DIMM slots. The 56-pin package provides ample I/O for wide buses, while the low propagation delay meets tight timing requirements.
Industrial Sensor Networks
For industrial control systems, the transceiver can manage bidirectional communication between a PLC and multiple sensor modules. The 3-State outputs allow multiple sensors to share a common bus, reducing wiring complexity.
Telecommunications Line Cards
In telecom equipment, this device buffers control and data signals between line interface units and the switch fabric. The wide voltage range accommodates various logic standards, and the robust drive capability handles long backplane traces.
Portable Medical Devices
The low-voltage operation makes it suitable for battery-powered medical monitors. The transceiver enables efficient data exchange between a sensor front-end and a processing unit, while the small BSSOP package fits compact PCBs.
