The AM2966JC is a non-inverting octal buffer from Advanced Micro Devices, featuring 3-State outputs. It operates from a 4.75V to 5.25V supply and provides 8-bit buffering in a 20-LCC (J-Lead) package. With a 12mA sink and 1mA source capability, it is designed to drive TTL-compatible loads. The device operates from 0°C to 70°C, making it suitable for commercial and industrial applications. Its surface-mount package is ideal for modern PCB assembly processes.
- Surface-Mount J-Lead Package: Enables automated assembly and reduces board space compared to DIP packages.
- Non-Inverting Buffer: Preserves signal integrity and simplifies logic design.
- 3-State Outputs: Facilitates bus multiplexing and isolation in complex systems.
- 12mA Sink Current: Provides strong drive capability for TTL loads and long traces.
Surface-Mount Bus Buffering
The 20-LCC package is ideal for space-constrained PCBs where through-hole components are impractical. Use it to buffer data lines in compact industrial controllers.
5V TTL Signal Distribution
Distribute clock or enable signals to multiple TTL devices. The non-inverting function preserves signal polarity, and 3-State outputs allow selective enabling.
Peripheral Interface Adapters
In legacy computer systems, buffer the data bus between a CPU and peripheral chips like UARTs or PIOs. The 12mA sink current ensures robust signal levels.
Automotive Engine Control Units (ECUs)
For vintage automotive electronics, this buffer can interface sensors to the ECU. Its 0°C to 70°C range covers standard automotive cabin environments.
Laboratory Power Supplies
Use it to buffer DAC output signals or to drive front-panel indicators. The J-Lead package allows easy soldering on prototype boards.
Networking Equipment
In older routers, buffer the management bus between the main processor and PHY chips. The 3-State outputs prevent bus conflicts during resets.
