Description

The SN74HC374NSR is an octal D-type latch designed for high-speed operation in digital circuits. This integrated circuit features eight data inputs (D0-D7) and eight latch outputs (Q0-Q7), allowing for the storage and retrieval of binary data. It operates with a supply voltage of 2V to 6V, making it compatible with various logic families.
The device has an active-low enable input (G) that controls when the input data is latched. When G is low, data on the inputs is transferred to the outputs on the next rising edge of the clock (CP), making it suitable for synchronous applications. The SN74HC374NSR is often used in data storage, buffering, and temporary data holding applications, providing reliable performance and low power consumption.
It comes in a surface-mount package (NSR), which is suitable for modern PCB designs. The device is part of the Texas Instruments HC (High-speed CMOS) family, known for its speed, low power, and high noise immunity.

Features

The SN74HC374NSR is an octal D-type transparent latch designed for high-speed data processing. Key features include:
1. Data Latching: It latches data on the rising edge of the clock input, allowing for temporary data storage.
2. High-Speed Operation: Designed for operation at high frequencies, suitable for fast digital circuits.
3. Low Power Consumption: Features low power dissipation, making it efficient for battery-operated applications.
4. Wide Supply Voltage Range: Operates with a supply voltage between 2V and 6V, compatible with various logic levels.
5. Output Drive Capability: Can drive multiple loads, providing strong output drive at high speed.
6. Tri-State Outputs: Outputs can be placed in a high-impedance state, allowing for easy bus interfacing.
7. TTL Compatibility: Compatible with TTL logic levels, ensuring integration with various digital systems.
8. Industrial Temperature Range: Suitable for a wide temperature range, enhancing reliability in diverse environments.
Overall, the SN74HC374NSR is ideal for applications requiring data storage, buffering, and interfacing in digital systems.

Package

The SN74HC374NSR is offered in a 20-pin SOIC (Small Outline Integrated Circuit) package type.

Pinout

The SN74HC374NSR is an octal D-type flip-flop that features 20 pins. It is designed for high-speed operation and can store data on the rising edge of a clock signal.
Pin functions include:
- 1-8 (Q0-Q7): Eight output pins for the stored data.
- 9 (GND): Ground connection.
- 10 (D0-D7): Eight input data pins that receive the D-type data.
- 11 (CLK): Clock input to control data sampling.
- 12 (CLR): Asynchronous clear input to reset all outputs to low.
- 13 (OE): Output enable pin, which when activated, allows the outputs to reflect the stored data.
- 14 (VCC): Power supply pin (typically +2V to +6V).
- 15-20 (NC): Not connected or reserved for future use.
This device is commonly used in digital circuits to register data and control flow.
