Octal D-Type Flip-Flop with Reset IC - 74HC273

The 74HC series 74HC273 is a 20-Pin Octal D-Type Positive Edge Trigger Flip-Flop with Reset IC having 2V to 6V Operating Voltage range with 5.2mA output current and high noise immunity. The device features clock (CP) and master reset (MR) inputs. The outputs Qn will assume the state of their corresponding Dn inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition.

A LOW on MR forces the outputs LOW independently of the clock and data inputs. Inputs include clamp diodes. This enables the use of current-limiting resistors to interface inputs to voltages in excess of VCC.

ADDITIONAL RESOURCES

1.What is the function of the 74HC273 IC?

  • The 74HC273 integrated circuit is an octal D-type flip-flop with clear. It is commonly used to store and transfer data in digital circuits. The 74HC273 integrated circuit has eight data input ports labelled D0 through D7.

2.How does the clear function of the 74HC273 IC work?

  • The 74HC273 IC's clear function allows the flip-flop to be reset to its initial state at any time. When the flip-clear flop's input (labelled "CLR") is set to a low logic level, all of its outputs are set to zero.

3.How is the 74HC273 different from the 74HC175 IC?

  • Both the 74HC273 and 74HC175 are D-type flip-flops, but they serve different purposes. The 74HC273 has a clear input, which allows the flip-flop to be reset, whereas the 74HC175 does not. Furthermore, the 74HC273 includes an active-high clock input, whereas the 74HC175 includes an active-low clock input. Finally, the 74HC273 includes an output-enable input, which allows the output pins to be tri-stated, whereas the 74HC175 does not.
