Functional Features

The SN74AS823ADWRE4 is an 8-bit D-type flip-flop with 3-state outputs. It features a high-speed operation and low-power consumption, making it suitable for various digital logic applications. The device has a clear input (CLR) to reset the flip-flop, and an output enable input (OE) to control the state of the outputs. The 3-state outputs allow multiple devices to be connected together without causing bus contention.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - 3-state outputs for bus sharing

Disadvantages: - Limited voltage supply range (4.5V to 5.5V) - Temperature limitations (-40°C to +85°C)

Working Principles

The SN74AS823ADWRE4 operates based on the principles of D-type flip-flops. When the clear input (CLR) is activated, the flip-flop is reset, and all outputs are forced to a low state. Data inputs (D0-D7) are sampled on the rising edge of the clock signal. The sampled data is then stored in the flip-flop and reflected at the outputs (Q0-Q7). The output enable input (OE) controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AS823ADWRE4 can be used in various applications, including: 1. Microprocessor systems 2. Data storage systems 3. Communication equipment 4. Industrial control systems 5. Automotive electronics
