Descriptions:

The HD74S175P is a high-speed quad D-type flip-flop with asynchronous clear functionality. It features edge-triggered operation, where data is transferred from the D input to the Q output on the positive clock edge. Each of the four flip-flops has a direct clear input (CLR) that resets the output to a low state when activated.

Features:

• Four Independent D-Type Flip-Flops
• Common Clock and Clear Inputs
• Schottky TTL for High-Speed Operation
• Asynchronous Clear Function
• Positive Edge-Triggered Clocking
• Compatible with Standard TTL Logic Levels
• Wide Operating Voltage Range (4.75V–5.25V)
• 16-Pin DIP Package

This IC is commonly used in data storage, synchronization, and sequential logic circuits in digital systems.
