The CD74FCT16952ATSM is a high-speed, non-inverting transceiver from Harris Corporation, designed for 5V logic systems. It features 2 channels with 3-State outputs, providing bidirectional data flow with bus isolation. Operating from 4.5V to 5.5V, it offers asymmetric output drive of 32mA source and 64mA sink, making it ideal for driving low-impedance or terminated buses. This transceiver is perfect for backplane communication, memory interfacing, and industrial control applications.
- High Sink Current (64mA): Provides superior drive for low-impedance and terminated bus lines.
- 3-State Outputs: Enables safe bus sharing and system isolation for redundancy.
- 74FCT High-Speed Logic: Ensures fast data transfer rates for high-performance systems.
- Bidirectional Operation: Simplifies board design by allowing data flow in both directions with a single IC.
High-Current Bus Transceiving
Use the CD74FCT16952ATSM in applications requiring high sink current (64mA). This is ideal for driving low-impedance bus lines or terminating resistors in high-speed digital systems.
Backplane Communication
In telecom backplanes, this transceiver can handle bidirectional data flow with robust drive capability. The 3-State outputs prevent bus contention during card insertion or removal.
Memory Interface
Interface a 5V memory controller with a high-capacitance memory bus. The asymmetric drive (32mA source, 64mA sink) is well-suited for terminating transmission lines.
Industrial Control Bus
In industrial automation, use this transceiver to communicate over a shared control bus. The high sink current ensures reliable logic-low levels even with long cable runs.
Data Acquisition Systems
Buffer data lines between an ADC and a processor. The transceiver allows bidirectional data flow, enabling configuration and data readback.
Redundant System Design
Implement bus isolation in redundant systems. The 3-State outputs allow a standby controller to disconnect from the bus while the primary controller is active.
