概要

Description

The SN74HC273NSR is a high-speed, low-power octal D-type flip-flop designed for use in digital circuits. It features eight D-type flip-flops, each with a common clock and an active-low asynchronous reset. The flip-flops store data on the rising edge of the clock signal, making them ideal for synchronous data storage applications.
This component operates at a wide voltage range of 2V to 6V, making it compatible with both TTL and CMOS logic levels. The SN74HC273NSR is housed in a 20-pin SOIC (Small Outline Integrated Circuit) package, allowing for efficient use of PCB space.
Key features include low static power consumption, high-speed operation with propagation delays typically under 15 ns, and the ability to handle fan-out requirements in complex circuits. It is commonly used in registers, counters, and memory applications. Overall, the SN74HC273NSR is a versatile and reliable choice for designers needing efficient data storage solutions in digital systems.

Features

The SN74HC273NSR is a high-speed CMOS D-type flip-flop with a 3-state output. Key features include:
1. Eight D Flip-Flops: It contains eight edge-triggered D flip-flops that can store data on the rising edge of a clock signal.
2. Asynchronous Inputs: It offers asynchronous set and reset inputs, allowing for immediate control over the flip-flops regardless of the clock state.
3. 3-State Outputs: The outputs can be configured to be in a high, low, or high-impedance state, facilitating bus systems and reducing loading on shared lines.
4. Wide Supply Voltage Range: Operates from 2V to 6V, making it suitable for various applications.
5. Low Power Consumption: Designed for low power, the device provides high-speed operation while minimizing energy usage.
6. TTL Compatible: Compatible with TTL outputs, ensuring integration with other TTL logic families.
7. Package Type: Available in a surface-mount 20-pin SOIC package.
These features make the SN74HC273NSR ideal for data storage and transfer applications in digital circuits.

Package

The SN74HC273NSR is packaged in a 20-pin TSSOP (Thin Shrink Small Outline Package).

Pinout

The SN74HC273NSR is an 8-bit D-type flip-flop with a pin count of 20. It features eight data inputs (D0 to D7), eight Q outputs (Q0 to Q7), and control inputs including a clock (CLK), a clear (CLR), and a preset (PRE).
When the clock input (CLK) transitions from low to high, the data at the D inputs is sampled and transferred to the Q outputs. The flip-flops can be asynchronously cleared or preset using the CLR and PRE inputs, respectively. Additionally, the device has an active-low enable (EN) input that allows the flip-flops to respond to the clock only when enabled.
This device is commonly used in digital applications for data storage and transfer, making it suitable for registers, counters, and memory applications. It operates within a voltage range of 2V to 6V and is designed for high-speed operation with low power consumption.
