Description

The SN74HC374N is an octal D-type flip-flop designed for high-speed digital applications. It features eight independent D flip-flops, each with a separate data input (D), clock input (CLK), and output (Q). The device captures data on the rising edge of the clock, allowing it to store binary information. It also includes a clear (CLR) and preset (PRE) function for resetting or setting the outputs, respectively.
The SN74HC374N operates on a wide voltage range (2V to 6V) and is part of Texas Instruments' 74HC series, which is known for high-speed operation and low power consumption. Its outputs are capable of driving TTL inputs and are designed to be compatible with various logic families. This device is commonly used in applications such as data storage, buffering, and temporary data holding in digital circuits. The package type for the SN74HC374N is typically a 20-pin dual in-line package (DIP).

Features

The SN74HC374N is a high-speed CMOS octal D-type flip-flop with a 3-state output. Key features include:
1. Octal Configuration: Contains 8 flip-flops with individual data inputs and outputs.
2. 3-State Outputs: Outputs can be set to high, low, or high-impedance, allowing for bus-oriented applications.
3. Edge-Triggered: Captures data on the rising edge of the clock input (CLK).
4. Asynchronous Clear: Each flip-flop can be cleared independently via the Clear (CLR) input.
5. Wide Operating Voltage Range: Typically operates from 2V to 6V, making it compatible with various logic levels.
6. Fast Switching: Offers high-speed performance, suitable for high-frequency applications.
7. Low Power Consumption: CMOS technology ensures low static and dynamic power draw.
8. DIP Package: Available in a dual in-line package for easy integration into circuits.
This device is ideal for data storage, timing applications, and digital logic circuits.

Package

The SN74HC374N is packaged in a dual in-line package (DIP) format, specifically a 20-pin DIP. This type of package is designed for through-hole mounting on circuit boards.

Pinout

The SN74HC374N is an octal D-type flip-flop with an active-high output enable and a common clock input. It features 20 pins, with the following key functions:
1. Data Inputs (D0-D7): Pins 2-9 receive the data.
2. Output Enable (OE): Pin 1 enables or disables the outputs.
3. Clock Input (CLK): Pin 10 triggers the flip-flops on the rising edge.
4. Outputs (Q0-Q7): Pins 11-18 provide the stored output data.
5. Ground (GND): Pin 20 connects to ground.
6. Vcc: Pin 19 connects to the positive supply voltage.
The flip-flops capture the input data on the rising edge of the clock signal and hold this data until the next clock pulse, making it suitable for data storage applications. The package type "N" indicates it is a dual in-line package (DIP).
