Visão Geral
Description
The SN74HC574PWR is packaged in a TSSOP (Thin Shrink Small Outline Package) configuration, making it suitable for space-constrained applications. This device is particularly useful in buffering and latching data in bus-oriented systems or other data-processing applications.
Key features include a clock (CP) input, which captures the input data on the rising edge, and an output enable (OE) input, which controls the state of the outputs. When OE is low, the outputs display the stored data; when OE is high, outputs are in a high-impedance state. This flexibility makes it ideal for use in a variety of digital systems needing stable data storage and retrieval.

Features
1. High-Speed Operation: Operates at a wide supply voltage range (2V to 6V) with typical propagation delays.
2. Low Power Consumption: Consumes minimal power due to the CMOS technology.
3. 3-State Outputs: Allows multiple devices to connect to the same bus, enabling output control via an output enable pin.
4. Latch-Up Performance: Exhibits excellent latch-up immunity, typically greater than 200 mA.
5. Input Clamping Diodes: Protects against static discharge and voltage spikes.
6. Wide Temperature Range: Functions efficiently over a temperature range of -40°C to 85°C, suitable for various applications.
7. Standard Pin Configuration: Compatible with industry-standard footprints for ease of design and integration.
8. Reliability: Manufactured with high reliability, ensuring consistent performance in various environments.
These features make it suitable for buffer, latch, and storage applications in digital systems.
Pinout
1. Pins 1-8 (D0-D7): Data inputs for each of the 8 flip-flops.
2. Pin 9 (GND): Ground connection.
3. Pin 10 (OE̅): Output Enable, active low. Controls the 3-state outputs.
4. Pins 11-18 (Q0-Q7): 3-state outputs corresponding to the data inputs.
5. Pin 19 (CLK): Clock input. Data is transferred to the outputs on the rising edge of the clock signal.
6. Pin 20 (VCC): Positive supply voltage.
The device is used in applications where temporary data storage is required, allowing data to be latched with a clock signal and selectively output. The 3-state capability enables multiple devices to share the same output lines.
