Description

The SN74HC273DWR is a high-speed CMOS octal D flip-flop with a common enable (E) and a clear (CLR) input. It belongs to Texas Instruments' 74HC family, designed for efficient digital logic applications. The device features eight D-type flip-flops that capture data on the rising edge of the clock (CLK) input. Each flip-flop has an individual output (Q) and its complement (Q̅).
The SN74HC273DWR operates within a voltage range of 2V to 6V, making it compatible with various logic levels, and it offers low-power consumption. The device supports synchronous operation, meaning that changes to the outputs occur in response to the clock signal while allowing for easy parallel data loading.
With a wide range of applications, it is commonly used in data storage, timing applications, and state machines. The package type is a TSSOP-20, suitable for space-constrained designs. Overall, the SN74HC273DWR is an efficient choice for systems requiring reliable state retention and control.

Pinout

The SN74HC273DWR is a high-speed CMOS D-type flip-flop with a total of 20 pins. It functions as an 8-bit latch, meaning it can store 8 bits of data. The key functions of its pins include:
1. Data Inputs (D0-D7): Pins 2-9 for data inputs.
2. Clock (CLK): Pin 10 for the clock input, which triggers the data to be latched.
3. Clear (CLR): Pin 11 for asynchronous clear, resets all outputs to low when activated.
4. Preset (PRE): Pin 12 for asynchronous preset, sets all outputs to high when activated.
5. Output (Q0-Q7): Pins 15-22 for the output states corresponding to the data inputs.
6. Ground (GND): Pin 20 for the ground connection.
7. VCC: Pin 14 for power supply connection.
The device operates with a supply voltage range of 2V to 6V and is designed for fast switching speeds.
