The CD74FCT16652TSM from Harris Corporation is a robust 2-channel non-inverting transceiver designed for 5V systems. It operates from 4.5V to 5.5V and provides strong output drive with 32mA source and 64mA sink current. The 3-State outputs allow multiple devices to share a common data bus safely. This IC is ideal for high-speed bus interfacing in telecommunications, industrial automation, and test equipment. Its 56-BSSOP package provides a compact footprint for dense PCB layouts. The CD74FCT family is known for its low power consumption and high noise immunity.
- High 64mA Sink Current: Drives low-impedance or heavily loaded buses with ease.
- Standard 5V Operation: Directly compatible with TTL and 5V CMOS logic.
- 3-State Outputs: Enables bus multiplexing and prevents data contention.
- Wide Temperature Range: Operates from -40°C to 85°C for industrial applications.
5V Bus Interfacing
Connect 5V microprocessors to memory or peripheral devices. The 4.5V-5.5V supply range ensures full compatibility with legacy 5V logic.
High-Current Bus Driving
Drive heavily loaded buses with up to 64mA sink current. This makes it ideal for backplane applications where multiple loads are present.
Telecommunications Equipment
Buffer data lines in telecom switches and routers. The high drive strength and 3-State outputs allow efficient multiplexing of multiple data sources.
Industrial Automation
In factory automation, this transceiver handles communication between PLCs and I/O modules, providing reliable signal transfer over long traces.
Test and Measurement
Use in ATE (Automated Test Equipment) to route test signals to different device-under-test pins. The 3-State outputs prevent bus conflicts during testing.
Data Acquisition Systems
Interface high-speed ADCs and DACs to a 5V data bus. The 32mA source / 64mA sink capability ensures fast charging of parasitic capacitances.
