Description

The 74HC74PW is a high-speed, dual D-type flip-flop with a direct clear and preset capability, part of the 74HC series of logic devices. It operates with a voltage range from 2V to 6V, making it compatible with TTL and CMOS logic levels. Each flip-flop within the IC has an independent data (D) input, clock (CP) input, preset (PRE) and clear (CLR) inputs, and complementary outputs (Q and Q̅).
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.

Pinout

The 74HC74PW is a dual D-type flip-flop IC with a positive-edge trigger. It has a total of 14 pins. Here's a brief overview of its pin functions:
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.
