Working Principles

The CY74FCT480BTPC is designed to amplify and buffer digital signals. It operates by receiving input signals on the A0-A7 pins and providing amplified output signals on the Y0-Y7 pins. The non-inverting nature of the buffer ensures that the output signal matches the input signal, but with increased current drive capability.

The output enable (OE) pin allows the user to control the output state. When OE is high, the outputs are enabled and actively driven. When OE is low, the outputs are in a high-impedance state, allowing other devices to drive the bus.

Detailed Application Field Plans

The CY74FCT480BTPC is commonly used in various applications, including:

1. Microprocessor/Controller interfacing
2. Memory address/data buffering
3. Clock distribution networks
4. Bus driving and buffering
