Working Principles
The SN74LVC373APWRG4 is an octal transparent latch that stores data on the rising edge of the clock input. The latch has 8 data inputs (D0-D7) and 8 corresponding outputs (Q0-Q7). When the clock input (CLK) transitions from low to high, the data present at the inputs is latched and stored in the outputs. The latch can be enabled or disabled using the output enable (OE) input. When OE is low, the outputs are active; when OE is high, the outputs are in a high-impedance state.
Detailed Application Field Plans
The SN74LVC373APWRG4 is widely used in various digital systems and applications, including:
- Microprocessors and microcontrollers
- Data storage systems
- Communication systems
- Industrial automation
- Automotive electronics
