The IDT74FCT16543TPA is a high-performance 2-channel, non-inverting transceiver from IDT. Operating from a 4.5V to 5.5V supply, it provides 3-State outputs with 32mA source and 64mA sink current capability. This device is ideal for bidirectional bus interfacing in 5V systems, offering robust signal drive for memory, telecom, and industrial applications. Housed in a compact 56-TFSOP package, it supports reliable operation from -40°C to 85°C.
- High Drive Current (64mA Sink): Ensures reliable signal integrity on heavily loaded buses, reducing the need for additional buffers.
- 3-State Outputs: Enables bus sharing and multiplexing in multi-master systems, preventing data corruption.
- Wide 4.5V to 5.5V Supply Range: Directly compatible with standard 5V logic, simplifying power design.
- Non-Inverting Architecture: Preserves signal polarity, reducing design complexity and potential errors.
- Industrial Temperature Range (-40°C to 85°C): Suitable for demanding industrial and automotive environments.
High-Density Bus Interfacing
Use the IDT74FCT16543TPA to interface between two 5V data buses in networking equipment. Its 2-channel, non-inverting architecture with 3-State outputs allows bidirectional data flow without signal inversion, simplifying PCB layout.
Memory Address/Data Buffering
In embedded systems, this transceiver buffers address and data lines between a 5V microcontroller and memory banks. The 64mA sink capability ensures robust drive for heavily loaded traces.
Server Backplane Communication
For server backplanes, the 3-State outputs enable multiple cards to share a common bus. The device's high drive current (32mA source, 64mA sink) maintains signal integrity over long traces.
Telecom Line Card Switching
In telecom line cards, this IC isolates and switches between redundant control paths. The 4.5V-5.5V range ensures compatibility with legacy 5V line card logic.
Industrial Control Module Isolation
In industrial PLCs, the transceiver provides a buffered interface between a 5V control core and field I/O modules. The -40°C to 85°C temperature range suits harsh factory environments.
Test & Measurement Equipment
