Working Principles

The 74HC244BQ-Q100,115 is an octal buffer/line driver IC that amplifies and buffers digital signals. It features non-inverting outputs and 3-state outputs, allowing multiple devices to share a common bus. When the Output Enable (OE) pin is low, the outputs are active and reflect the input signals. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the bus.

Detailed Application Field Plans

The 74HC244BQ-Q100,115 can be used in various applications, including: 1. Data communication systems 2. Memory interfacing 3. Address decoding 4. Bus driving and buffering 5. Clock distribution
