概述

Description

The SN74HC273N is an octal D-type flip-flop designed for high-speed data storage and transfer in digital circuits. It features eight flip-flops that can individually store one bit of data each, controlled by a common clock input. The device uses positive-edge triggering, meaning data is captured on the rising edge of the clock signal.
This flip-flop has an active-low asynchronous reset (CLR) that allows for immediate clearing of all outputs, and an enable (G) pin that controls the data flow to the outputs based on its state. The SN74HC273N is part of Texas Instruments' HC (High-speed CMOS) series, offering low power consumption and high-speed operation, making it suitable for various applications in computing, telecommunications, and consumer electronics.
It operates within a supply voltage range of 2V to 6V and is available in a 20-pin DIP package, making it easy to integrate into circuit designs. It is widely used in register files, memory devices, and data buffering applications.

Features

The SN74HC273N is a high-speed CMOS quad D-type flip-flop with the following key features:
1. Quad D Flip-Flop: Contains four D flip-flops, which allow for the storage of binary data.
2. Positive Edge Triggered: Data on the D inputs is transferred to the Q outputs on the rising edge of the clock signal.
3. Asynchronous Inputs: Features active-low preset (PRE) and clear (CLR) inputs for asynchronous operation, allowing immediate setting or resetting of outputs.
4. High-Speed Operation: Designed for high-speed performance, with typical propagation delays in the nanoseconds range.
5. Wide Supply Voltage Range: Operates with a supply voltage of 2V to 6V, making it suitable for various applications.
6. Low Power Consumption: CMOS technology results in low static and dynamic power consumption.
7. Standard 16-Pin DIP Package: Available in a standard dual in-line package for easy integration into circuits.
These features make the SN74HC273N suitable for applications in digital circuits, data storage, and state machine designs.

Package

The SN74HC273N is packaged in a 20-pin Dual In-Line Package (DIP) configuration. This package type allows for easy integration onto printed circuit boards and is commonly used in various digital circuits.

Pinout

The SN74HC273N is an 8-bit D-type flip-flop with a pin count of 20. It features two main functions:
1. Data Storage: It can store 8 bits of data (D0 to D7) and transfer the data to the output (Q0 to Q7) on a clock edge (CLK).
2. Control Signals: It includes additional pins for control functions:
- CLK: Clock input for data transfer.
- CLR: Asynchronous clear that resets all outputs to low.
- PRE: Asynchronous preset that sets all outputs high.
The device is commonly used in digital circuits for temporary data storage and is characterized by fast switching speeds and low power consumption. The flip-flops are triggered on the rising edge of the clock signal.
