Présentation
Description
The device is characterized by its ability to store and toggle data on the rising edge of the clock pulse, provided that the preset and clear inputs are inactive (high state). The preset input, when activated, sets the output Q to high, while the clear input resets it to low. These features make the 74HC74PW suitable for applications in counters, registers, and data storage.
The package style for the 74HC74PW is typically a TSSOP (Thin Shrink Small Outline Package), which provides a compact form factor for space-constrained applications. Its robust performance and wide availability make it a popular choice in digital electronics projects.

Features
1. Logic Family: High-Speed CMOS (HC).
2. Configuration: Dual flip-flop with individual data (D), clock (CP), set (SD), and reset (RD) inputs.
3. Supply Voltage: Operates at a voltage range of 2V to 6V.
4. Propagation Delay: Fast switching with a typical propagation delay of around 15ns at 5V.
5. Output Capability: Standard output drive with symmetrical drive characteristics.
6. Input Levels: Compatible with TTL inputs at 5V supply.
7. Power Consumption: Low power consumption due to CMOS technology.
8. Package Type: Available in TSSOP (Thin Shrink Small Outline Package), offering compact size for space-constrained applications.
9. Temperature Range: Operates over a wide temperature range, typically from -40°C to +125°C.
10. Applications: Commonly used in applications requiring data storage, data transfer, and synchronization.
These features make the 74HC74PW suitable for general-purpose digital applications requiring reliable flip-flop operations.
Pinout
1. GND (Pin 7): Ground connection.
2. VCC (Pin 14): Supply voltage.
3. D1, D2 (Pins 2, 12): Data inputs for the first and second flip-flop, respectively.
4. Q1, Q2 (Pins 5, 9): Outputs of the flip-flops.
5. Q1', Q2' (Pins 6, 8): Inverted outputs of the flip-flops.
6. CLK1, CLK2 (Pins 3, 11): Clock inputs for the flip-flops. The data is transferred to the output on the rising edge of the clock.
7. PRE1, PRE2 (Pins 4, 10): Asynchronous set inputs. When low, this sets the output Q to high, independent of the clock.
8. CLR1, CLR2 (Pins 1, 13): Asynchronous reset inputs. When low, this sets the output Q to low, independent of the clock.
The 74HC74PW is used in applications requiring data latching, such as shift registers, counters, and data storage.
