SN74HC273N Typical application Circuitry

SN74HC273N

The SN74HC273N is an octal D-type flip-flop with a clear function, primarily used for storage of binary information. Data is sent from the input to the output of each edge-triggered flip-flop on the rising edge of the clock pulse. The clear function is asynchronous and can be used to reset the flip-flops. This chip is ideal for applications where data needs to be stored temporarily and accessed rapidly.

Functional Overview

The SN74HC273N's core functionality revolves around its ability to securely hold and process eight individual bits of data. The information present at its input pins is captured and held stable at the output pins upon the arrival of a clock pulse.

Application Landscape

The SN74HC273N is versatile, finding utility in systems requiring temporary data storage or transfer, such as computer systems, registers, relay control, and buffer memory storage.

Characteristic Parameters

- Supply Voltage (Vcc): Typically between 2V and 6V.

- Input High Voltage (VIH): Generally above 2V for a logical '1'.

- Input Low Voltage (VIL): Typically below 0.8V for a logical '0'.

- Output Current (IO): Capable of driving up to 6 mA.

- Propagation Delay (tPHL/tPLH): Duration varies based on Vcc and load characteristics.

Circuit Integration: Buffer Register in a Microprocessor System

In this application, the SN74HC273N is utilized as a buffer register, providing a means to store data temporarily during microprocessor operations.

1. Power Supply Integration

- Vcc (Pin 20): Connect this pin to a +5V power source.

- Ground (Pin 10): This pin should be connected to the system ground.

2. Clock Signal Configuration

- Clock Input (CLK, Pin 11): Link this pin to the system clock. Data is latched at the rising edge of the clock signal.

3. Data Input Connection

- Data Inputs (D0-D7, Pins 2-7, 15-18): Connect these to the data lines from the microprocessor or preceding logic circuit.

4. Output Utilization

- Data Outputs (Q0-Q7, Pins 19, 20, 22-25, 27, 28): Route these pins to the subsequent part of the system where the stored data is required.

5. Clear Function Activation

- Clear Input (CLR, Pin 1): Connect this pin to a control signal for resetting the flip-flops. A low signal on this pin clears the flip-flops asynchronously.

Design Nuances

When incorporating the SN74HC273N into a circuit, several critical aspects need consideration:

1. Stable Power Provision: Ensure that the power supply is free from noise, as instability can lead to unpredictable behavior.

2. Clock Signal Integrity: The clock signal should have minimal jitter and sharp edges to avoid misinterpretation by the flip-flops.

3. Signal Isolation: Employing a decoupling capacitor near the Vcc pin is recommended to filter out any transient noise.

4. Clear Signal Management: The clear function must be used judiciously, ensuring that it doesn't inadvertently reset the flip-flops during normal operation.

In summary, the SN74HC273N is a fundamental component in digital electronics, particularly effective in situations demanding rapid and reliable data storage. Its role as a buffer register in a microprocessor system underlines its capability to interface seamlessly with complex digital systems. Meticulous attention to power supply quality, clock signal precision, and input management ensures that the SN74HC273N performs optimally, cementing its position as a robust and indispensable element in digital circuit design. Whether it's for buffering, temporary storage, or data transfer, the SN74HC273N is a versatile and reliable choice.
