The 54S175DMQB is a high-speed quad D flip-flop with clear and complementary outputs from the 54S series. This TTL device provides four independent D-type flip-flops, each with a direct clear input and complementary Q and /Q outputs. It is characterized for operation over the full military temperature range (-55°C to +125°C). The 54S175DMQB is suitable for registers, counters, and control circuits requiring high-speed operation and complementary outputs.

Applications

• Shift Registers
• Storage Registers
• Counters
• Control Logic
• Data Buffering

Features

• High Speed Operation: Fast propagation delays for time-critical applications.
• Quad D Flip-Flops: Contains four independent D-type flip-flops.
• Direct Clear Input: Allows asynchronous clearing of all flip-flops.
• Complementary Outputs: Provides both Q and /Q outputs for versatility.
• Military Temperature Range: Guaranteed performance over -55°C to +125°C.

Benefits

• Versatile Logic Function: Suitable for a wide range of digital circuits.
• Simplified Circuit Design: Integrates four flip-flops in a single package.

Additional Details

The 54S175DMQB operates from a 5V power supply. Data is loaded into the flip-flops on the positive-going edge of the clock pulse. The clear input, when low, resets all flip-flops regardless of the clock or data inputs. The device comes in a 16-pin DIP package. It is constructed using bipolar technology for high-speed performance and is typically used in applications where speed is a primary requirement.
