The CD74FCT16543CTSM is a high-speed, 2-channel non-inverting transceiver from Harris Corporation. Operating from a 4.5V to 5.5V supply, it features 3-State outputs and robust drive capability of 32mA source and 64mA sink. This makes it ideal for 5V bus interfacing, memory systems, and industrial control applications. The device is available in a compact 56-BSSOP package and operates over -40°C to 85°C.
- High Drive Current (64mA Sink): Drives heavily loaded buses and peripheral devices without additional buffers.
- 3-State Outputs: Enables bus multiplexing and bidirectional data flow in shared-bus architectures.
- Wide Temperature Range (-40°C to 85°C): Suitable for industrial and automotive environments.
- 5V Operation: Directly compatible with legacy 5V logic systems, simplifying design.
High-Speed 5V Bus Interfacing
Use the CD74FCT16543CTSM to interface between two 5V buses in computing and telecom equipment. Its 64mA sink capability ensures signal integrity on heavily loaded backplanes.
Server Memory Controllers
In server systems, this transceiver buffers address and data lines between the memory controller and DIMM modules, providing the necessary drive strength for reliable operation.
Industrial Control Backplanes
For PLC and industrial control backplanes, the 3-State outputs allow multiple boards to share a common data bus without contention, while the wide temperature range supports harsh environments.
Telecommunications Switching
In telecom switches, the device can be used for bidirectional data flow between line cards and the switching fabric, ensuring low propagation delay and high noise immunity.
Test and Measurement Equipment
In ATE (Automated Test Equipment), this transceiver can route test vectors to multiple pins, with the 3-State feature enabling tri-state control for bidirectional test buses.
5V Peripheral Driver
With 32mA source and 64mA sink, it can directly drive LEDs, relays, or small motors in 5V logic systems, reducing the need for external driver ICs.
