Working Principles

The SN74AS876DWG4 is an 8-bit D-type flip-flop with 3-state outputs. It operates on a positive-edge triggered clock input, which latches the data inputs (D0-D7) into the flip-flop on each rising edge of the clock signal. The asynchronous clear input (OE) allows for resetting the flip-flop to a known state.

The 3-state outputs (Q0-Q7) can be enabled or disabled using the output enable input (OE). When the OE input is high, the outputs are active and reflect the current state of the flip-flop. When the OE input is low, the outputs are in a high-impedance state, allowing multiple devices to share a common bus without interfering with each other.

The SN74AS876DWG4 is commonly used in various digital logic applications, including:

  1. Data storage and retrieval systems
  2. Address decoding circuits
