A flip-flop (or latch) is a digital logic circuit that has two stable states and can be used to store binary data. The 74VHC273TTR is a D-type flip-flop integrated circuit used for flip-flop applications such as data storage. This article looks at the 74VHC273TTR application fields and working principles.

74VHC273TTR application fields

The 74VHC273TTR is a high speed CMOS D-type flip-flop with buffered inputs. It is compatible with most TTL logic families, and is designed for high performance and temperature range. It is commonly used in a wide range of electronic applications, including data input and storage, signal conversion, signal transmission, and data output control.

The 74VHC273TTR is particularly suitable for memory and signal processing applications such as microprocessor and microcontroller systems, digital signal processing, and logic control. In such applications it can be used to store a single bit of information (a bit), a binary sequence, or a multi-bit binary word. It is also used in other applications such as resettable counters and synchronous data transmission.

74VHC273TTR Working Principle

The 74VHC273TTR operates with a supply voltage of 3V to 5.5V and a supply current of 1µA. It features a true output and a data input for positive-edge triggering. The flip-flop is clocked when the clock signal goes from low to high. When the clock signal goes from high to low, the data is transferred from the data input (D) to the Q output.

The 74VHC273TTR also has two reset pins (R1 and R2), which allow for a reset of the flip-flop if either pin is active (low). When the resetpin is active, the Q output is forced to a logic low. The other input, named the master reset (MR), allows a disconnection of the outputs from the data input and reset pins. This feature enables the synchronization of multiple flip-flops.

In operation, the 74VHC273TTR flip-flop stores data on the rising edge of the clock (positive edge triggering). When a logic low signal is applied to the reset pin, the outputs are reset to low. If a logic high signal is applied to the master reset pin, the outputs become floating and are no longer affected by any of the inputs.

The 74VHC273TTR offers excellent performance in terms of speed and power consumption, making it a popular choice for a wide range of electronic applications. Its features make it well-suited for use in data storage, signal conversion, and data output control, as well as other applications.
