The MC74HC273AF is a sophisticated logic IC chip designed with eight edge triggered flip-flops, each with a pair of 3-state outputs. It is made by Motorola/NEC as part of their popular MC74HC family of devices. The MC74HC273AF is an ideal choice for industrial, telecommunications, and consumer applications needing flip-flop functionality. The MC74HC273AF contains two sets of four flip-flops, arranged such that all eight output pins share the same broad group of logic inputs and provide independent output functions. The external logic inputs can be used to control the flip-flops in various ways, including set and reset synchronous operations, as well as combinatorial functions. The outputs may be used either as logic, wide-open-collector, or tri-state outputs. The MC74HC273AF has a maximum operating voltage of 5.5V and minimum operating voltage of 2.7V, a maximum current draw of 10mA and a maximum frequency of 50MHz, making it suitable for both low and high speed logic operations in a wide variety of logic applications. The MC74HC273AF uses a combination of logic and flip-flop circuitry to maintain a false (latched) combination logic level until reset or cleared. When the reset or clear input is presented, it forces the flip-flops to reset to the “OFF” or “0” state, regardless of the state of the other inputs. This allows for a two-step reset process that allows the NO reset/set input to force the flip-flop back to the “ON” state. The MC74HC273AF is designed with an internal phase-locked loop (PLL) to provide a steady clock rate as long as the input voltages remain within the specified range. This PLL circuit increases the performance of the circuit by eliminating any jitter or variations caused by the input voltage. Additionally, the PLL provides a means of bypassing the jitter suppression logic when necessary. The MC74HC273AF is designed with an open-drain architecture. An open-drain architecture is a type of logic circuit that provides an output that is either open or pulled to ground (low). This architecture allows for a greater flexibility and speed of operation since the outputs are always able to be directly determined. Additionally, this architecture greatly reduces the power consumption compared to other types of logic circuits. In summary, the MC74HC273AF is an ideal choice for industrial, telecommunications, and consumer applications needing flip-flop functionality. It is able to provide maximum operating voltages of 5.5V, a maximum current draw of 10mA, and a maximum frequency of 50MHz. The integrated PLL provides a steady clock rate, allowing the circuit to bypass the jitter suppression logic when needed. It also features an open-drain architecture, reducing the power consumption compared to other types of logic circuits.
