The post 74LS273 appeared first on The Geek Pub.

]]> 74LS273 replacement chip. DIP-20. Octal D-type flip-flop with clear.

The 74LS273 is a popular integrated circuit (IC) that belongs to the 74xx series of TTL (Transistor-Transistor Logic) digital logic chips. It specifically falls under the category of flip-flops and latches. The 74LS273 is an octal D-type flip-flop with a clear input, meaning it has eight individual flip-flops in a single package.

Here are some key features and characteristics of the 74LS273:

  1. Flip-Flop Type: D-type (Data or Delay Flip-Flop)
  2. Number of Flip-Flops: 8 (Octal)
  3. Inputs:
    • D0 to D7: Data inputs for each flip-flop
    • CP (Clock): Clock input for all flip-flops
    • MR (Master Reset): Master reset input (active-low)
  4. Outputs:
    • Q0 to Q7: Individual flip-flop outputs
    • Q̅0 to Q̅7: Complementary outputs
  5. Clear Function: The 74LS273 includes a Master Reset (MR) input, which is active-low. When MR is pulled low, it clears all the flip-flops, setting their outputs to a low state.
  6. Clock Edge Triggering: The flip-flops are triggered on the rising edge of the clock signal (CP).
  7. Operating Voltage: The typical operating voltage is 5V.
  8. Package: The 74LS273 is available in various package types, such as DIP (Dual In-line Package) and SOP (Small Outline Package).

Applications of the 74LS273 include data storage, address decoding, and general-purpose sequential logic applications where the need for multiple flip-flops is present.

It’s important to note that as of my last knowledge update in January 2022, technology and product specifications might have evolved, and there might be newer versions or alternatives available. Always refer to the latest datasheet or documentation for the most accurate and up-to-date information.
