• Serial-to-parallel conversion
• Parallel-to-serial conversion
• Data storage
• Sequence generation
• Digital delay lines

Features:

• 4-Bit Parallel Access
• Serial and Parallel Data Entry
• Parallel Data Output
• Asynchronous Master Reset
• J-K Serial Input

Benefits:

• Versatile Data Handling: Allows both serial and parallel data input and output, providing flexibility in system design.
• Multiple Operating Modes: Can function as a shift register, storage register, or parallel-to-serial converter.
• Simplified System Design: Integrated asynchronous master reset simplifies initialization and error recovery.
• Easy cascading: Multiple register cascading is possible for increased bit storage.

Additional Details:

The M74LS195AP operates within a supply voltage range of 4.75V to 5.25V and is characterized for operation from 0°C to 70°C. It is housed in a 16-pin DIP package. The device includes parallel data inputs (A-D), serial inputs (J, K), a parallel enable (PE) input, a clock (CP) input, and parallel outputs (QA-QD). A master reset (MR) input allows for asynchronous clearing of the register. The parallel enable input controls the parallel loading of data.
