Functional Features
The SN74ALS561ADWR is an 8-bit transparent latch with 3-state outputs. It allows data to be latched and held when the latch enable (LE) input is high. The latch is transparent when the LE input is low, allowing the data inputs to pass through to the outputs. The output enable (OE) input controls the 3-state outputs, enabling or disabling them as needed.
Advantages and Disadvantages
Advantages: - High-speed operation - Low-power consumption - 3-state outputs for bus-oriented applications - Wide operating temperature range
Disadvantages: - Limited voltage supply range (4.5V to 5.5V) - Propagation delay time may affect timing-sensitive applications
Working Principles
When the latch enable (LE) input is high, the SN74ALS561ADWR latches the data inputs (D0-D7) and holds them at the outputs (Q0-Q7). When the LE input is low, the latch becomes transparent, allowing the data inputs to pass through to the outputs. The output enable (OE) input controls the 3-state outputs, enabling or disabling them as required.
Detailed Application Field Plans
The SN74ALS561ADWR is commonly used in various digital systems where data needs to be latched and held temporarily. It finds applications in:
- Microprocessors and microcontrollers
- Data storage systems
- Communication equipment
- Industrial automation
- Automotive electronics
