Pinout
- Pin Count: The 74HC273D comes in a 20-pin SOIC (Small Outline Integrated Circuit) package.
- Function:
- It consists of eight edge-triggered D-type flip-flops with individual D inputs and Q outputs.
- The device captures the value on each D input on the rising edge of the clock (pin 11) and holds it until the next rising edge.
- The output of each flip-flop can be cleared asynchronously by applying a low signal to the master reset (MR) pin (pin 1).
The 74HC273D is widely used in applications requiring temporary data storage, data synchronization, and state machine design.
