74LS174DC – FSC

Overview

The FSC 74LS174DC is a hex D-type flip-flop IC designed for high-speed data buffering and storage applications within TTL systems. Its core functionality lies in its positive-edge-triggered clocking mechanism, ensuring precise data capture at the D inputs and subsequent propagation to the Q outputs. A critical design consideration when integrating this component is the inherent trade-off between its robust TTL noise immunity and the power dissipation, which can become significant in densely populated, high-frequency designs, necessitating careful thermal management and power supply decoupling.

Key Features

• Six independent D-type flip-flops
• Buffered clock and direct clear inputs
• Individual data inputs per flip-flop
• Single-rail Q outputs
• Typical clock frequency: 40 MHz
• Physical dimensions: Standard 16-pin DIP package

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Buffer and storage registers for data acquisition systems
• Serial-to-parallel conversion in communication interfaces
