The HD74HC597FPEL-SOP5.2 is an 8-bit shift register with a parallel output latch belonging to the Hitachi High-speed CMOS logic family. This device combines the functions of a serial-in, parallel-out shift register with an 8-bit storage register. Data is shifted serially into the shift register on each positive-going clock edge. The data in the shift register can then be transferred to the output latch by applying a HIGH level to the latch enable (LE) input. The parallel outputs (QA-QH) provide the stored data.

Applications

• Serial-to-parallel data conversion
• Remote control systems
• Display drivers
• Keyboard scanning
• Interface circuits

Features

• 8-bit shift register: Stores eight bits of serial data.
• Parallel output latch: Provides parallel outputs for the stored data.
• Serial input (SI): Accepts serial data.

• Efficient data storage and retrieval.

Additional Details

The HD74HC597FPEL-SOP5.2 is available in a SOP (Small Outline Package). This package provides a compact footprint for surface-mount applications. Data is shifted into the register on the positive-going edge of the clock pulse. When the latch enable (LE) input is HIGH, the data in the shift register is transferred to the output latch, and the parallel outputs (QA-QH) reflect the stored data. When LE is LOW, the output latch retains its previous state. The device is widely used in applications requiring serial-to-parallel data conversion, such as driving displays, interfacing with microcontrollers, and implementing remote control systems. Proper decoupling with capacitors close to the power supply pins is recommended. Refer to the datasheet for detailed electrical characteristics, timing diagrams, and application notes. The device provides a reliable and efficient solution for serial-to-parallel data conversion in various digital systems.
