Logic buffers are integrated circuit semiconductor devices with integral back-to-back bi-inverters designed to provide a basic logic gate to pass intact input into output. These bus buffers come in surface mount and through-hole mounting types with inverting and non-inverting configurations. In addition, they feature various pin numbers ranging from 5 to 100 with different voltage supplies.
How do they work?
Buffers house drivers and transceivers that use robust high and low attributes for input regeneration. These semiconductors act as weak signal sources with limited current sources, increasing the signal current capacity for driving loads.
What are the types of buffers?
Buffers have a variety of types based on their configurations, combinations with converters, input/output support, and logic families’ support. They differ based on the channel numbers that support multiple inputs and outputs like DTL and CMOS, along with supporting logic families, including HEF, TTL, and HC.
A bus buffer is another type of buffer designed to connect various data sources to each bus and is chosen based on its logical high, low, and high impedance that supports multiple input/output, families, and pin numbers that are configured on the integrated circuit.
Typical applications of buffers:
- The primary function of a buffer is to regenerate weak output from non-restoring logic and the input, exploiting a strong low and high.
- They are also ideal for increasing circuits’ propagation delays using significant capacitive load driving.
They are also primarily found in:
- TV and video equipment
- Automatic test equipment
- Portable equipment
- Board test systems
- Industrial controls
- Instrumentation and characterization equipment
- Semiconductor test systems.
