The NCA8T245-DTSXR is a single-channel bidirectional transceiver from the 245 logic family, designed for seamless voltage translation and bus interfacing. It operates from 1.65V to 5.5V, with 3-State outputs and 32mA drive capability. Housed in a compact 24-TSSOP package, it supports industrial temperature ranges (-40°C to 125°C). This device is ideal for mixed-voltage systems, IoT devices, and industrial control applications where reliable bidirectional data flow is critical.
- Wide 1.65V to 5.5V Supply Range: Enables seamless level shifting between 1.8V, 2.5V, 3.3V, and 5V logic domains.
- 3-State Outputs: Allows bus sharing and isolation, preventing data contention in multi-device systems.
- High 32mA Drive: Can drive heavy capacitive loads and long PCB traces without signal degradation.
- Extended Temperature Range (-40°C to 125°C): Suitable for automotive and industrial environments.
Level Shifting for Mixed-Voltage Systems
With a 1.65V to 5.5V supply, the NCA8T245-DTSXR can translate signals between a 1.8V microcontroller and a 3.3V or 5V peripheral, eliminating the need for separate level shifters.
Bidirectional Data Bus in IoT Devices
In IoT gateways, this transceiver enables bidirectional communication between a low-power sensor hub (1.8V) and a main application processor (3.3V), ensuring reliable data exchange.
Hot-Swap Backplane Interfacing
The 3-State outputs allow the device to be placed on a backplane bus, where multiple cards can be isolated or connected without disrupting active communications.
Battery-Powered Portable Electronics
Operating down to 1.65V, it is ideal for battery-operated devices, buffering signals between an energy-efficient MCU and higher-voltage display or memory modules.
Industrial Sensor Networks
In industrial settings, it can interface 3.3V logic with 5V legacy sensors, providing robust signal translation over extended temperature ranges (-40°C to 125°C).
FPGA Configuration Interfaces
Use it to buffer and translate configuration data between an FPGA (1.8V I/O) and an external configuration flash (3.3V), ensuring reliable boot-up sequences.
