The AM2966SC is a dual non-inverting buffer designed for 5V systems. It features 3-State outputs and provides a low-current input (1mA) with a robust 12mA output drive. Housed in a 20-pin SOIC package, it is suitable for bus-oriented applications, signal buffering, and driving moderate loads in TTL logic environments.
- 3-State Outputs: Enables connection to shared data buses, preventing signal contention and allowing multiple drivers.
- Non-Inverting Buffer: Preserves the original logic level, simplifying design and debugging.
- Dual Channel Design: Provides two independent buffers in one package, saving board space and cost.
- Standard 5V Operation: Directly compatible with legacy TTL and 5V CMOS logic families.
5V TTL Bus Interfacing
Use the AM2966SC to buffer address or data lines between a 5V microprocessor and memory or peripheral devices. The 3-State outputs allow multiple devices to share the same bus without contention.
Signal Buffering for High-Capacitance Loads
When driving long PCB traces or multiple inputs, the buffer's 12mA sink capability at 5V ensures signal integrity by providing the necessary drive current to overcome parasitic capacitance.
Memory Address Line Driving
In legacy 5V memory systems, this buffer can fan out address signals to multiple memory banks, ensuring clean, non-inverted logic levels and preventing loading of the source.
Industrial Control Logic Isolation
In 5V industrial controllers, the AM2966SC can isolate different logic sections, providing a buffered interface between a control unit and output stages, with the 3-State feature enabling safe disconnection.
Test Equipment and Instrumentation
For bench test equipment operating at 5V, this buffer can drive external loads or provide a clean, buffered copy of a signal for monitoring purposes, thanks to its non-inverting nature.
- Q: What is the logic family of the AM2966SC?
- A: The AM2966SC is a bipolar logic buffer, not a standard 74-series CMOS family. It operates at a fixed 5V supply.
- Q: What is the function of this IC?
- A: It is a dual (2-channel) non-inverting buffer with 3-State outputs, ideal for bus driving and signal isolation.
- Q: How many channels does it have?
- A: It contains 2 independent buffer channels.
- Q: What is the output type?
- A: The outputs are 3-State, allowing connection to shared buses with high-impedance (Hi-Z) state.
- Q: What is the operating voltage range?
- A: The supply voltage range is 4.75V to 5.25V, making it suitable for standard 5V TTL systems.
- Q: What package is available?
- A: It comes in a 20-pin SOIC package (0.295", 7.50mm width).
