The IDT74FCT16827ETPA is a dual non-inverting buffer from IDT, engineered for high-speed 5V logic systems. It provides 16 bits of buffering with 3-State outputs, enabling efficient bus isolation and signal driving. Operating from 4.5V to 5.5V, it delivers 32mA sink and 64mA source current, making it ideal for driving heavy loads. The 56-TFSOP package is suitable for space-constrained designs in industrial, telecom, and computing applications.
- High Output Drive (32mA/64mA): Capable of driving large capacitive loads and long bus lines, ensuring reliable signal transmission.
- 3-State Outputs: Allows multiple buffers to be connected to the same bus, facilitating system expansion and redundancy.
- Non-Inverting Buffer: Preserves signal polarity, simplifying logic design and reducing potential errors.
- Industrial Temperature Range: Operates from -40°C to 85°C, suitable for harsh environments.
High-Drive Bus Buffering
Use the IDT74FCT16827ETPA to buffer address or data buses in 5V microprocessor systems. Its 32mA sink and 64mA source capability provides excellent drive for high-capacitance loads.
Clock Distribution
Buffer and fan out clock signals to multiple peripherals. The non-inverting function preserves clock polarity, while the strong output drive minimizes skew.
Memory Address Buffering
In DRAM/SRAM systems, this buffer isolates the memory array from the controller, reducing loading effects and improving signal quality.
Industrial Sensor Interfaces
Interface 5V sensors and encoders to a control logic board. The buffer provides electrical isolation and protects sensitive logic from external noise.
Telecom Line Cards
Buffer control and status signals between line interface units and the main switch fabric. The 3-State outputs allow multiple line cards to share a common maintenance bus.
Automotive ECU Signal Conditioning
In automotive ECUs, buffer 5V logic signals from various sensors and actuators, ensuring reliable operation over the -40°C to 85°C temperature range.
