Functional Features

The 74HC273PW,118 is a positive-edge triggered D-type flip-flop with reset and preset inputs. It operates at high speed while consuming low power. The flip-flop has eight outputs (Q0-Q7) and an inverted output (Q7'). It also features an output enable input (OE) for multiplexing or cascading multiple flip-flops.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data processing - Low power consumption reduces energy usage - Reset and preset inputs provide flexibility in controlling the flip-flop's state - Output enable input enables multiplexing and cascading capabilities

Disadvantages: - Limited number of outputs may restrict certain applications requiring more outputs - TSSOP-20 package may be challenging to solder for some users

Working Principles

The 74HC273PW,118 operates based on positive-edge triggering. When a clock pulse is applied to the CP input, the data present at the D0-D3 inputs is transferred to the Q0-Q3 outputs. The Q4-Q7 outputs retain their previous states until a reset or preset signal is received. The flip-flop can be reset by applying a low-level signal to the MR input or preset by applying a low-level signal to the PR input.
