Working Principles

The SN74AS876DWRE4 is an 8-bit D-type flip-flop with 3-state outputs. It stores data on the rising edge of the clock pulse (CP) input. The stored data can be cleared using the active LOW clear (CLR) input. The output enable (OE) input controls the activation of the 3-state outputs (Q0-Q7). When OE is HIGH, the outputs are in a high-impedance state, allowing multiple devices to share the same bus.

Detailed Application Field Plans

The SN74AS876DWRE4 is commonly used in various digital systems, including:

1. Microprocessors and microcontrollers
2. Data storage systems
3. Communication equipment
4. Industrial automation
5. Automotive electronics
