The MM74HC597M is an 8-bit serial-to-parallel/parallel-to-serial shift register with latched 3-STATE outputs. This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit storage register. Separate clocks are provided for both the shift and storage registers. A serial output (Q7S) allows cascading for longer shift registers. The 3-STATE outputs are controlled by an Output Enable (OE) input.

Applications:

• Serial-to-parallel data conversion
• Parallel-to-serial data conversion
• Remote display drivers
• Keyboard scanning
• Microprocessor interfacing

Features:

• 8-Bit Serial-to-Parallel/Parallel-to-Serial Conversion
• Separate Shift and Storage Register Clocks
• 3-STATE Outputs for Bus Interfacing
• Serial Output for Cascading
• High Speed Operation
• TTL Compatibility

Benefits:

• Flexible Data Conversion: Supports both serial-to-parallel and parallel-to-serial data transfer.
• Independent Clocks: Allows precise control over shift and storage operations.
• Easy Bus Interfacing: 3-STATE outputs simplify connection to microprocessor buses.
• Expandable Architecture: Serial output allows cascading multiple devices for longer data words.
• High Performance: Provides fast data transfer rates for demanding applications.

Additional Details:

The MM74HC597M is particularly useful in applications requiring data to be transferred between serial and parallel formats. The separate shift and storage register clocks provide maximum flexibility in data manipulation. The 3-STATE outputs allow multiple devices to share a common data bus without contention.

Key Specifications:

• Supply Voltage: 2V to 6V
• Clock Frequency: Up to 25 MHz
• Operating Temperature Range: -40°C to +85°C
