　　Product Features and Benefits

　　1. 8-bit Serial Input: Allows data input from a serial data source for a wide range of applications.

　　2. 8-bit serial or parallel output: Provides flexible data output options to meet different application requirements.

　　3. Memory registers with tri-state outputs: When the output enable (OE) is low, the data in the memory registers will appear at the outputs; when it is high, the outputs are in a high impedance state.

　　4. Direct zero function for shift register: Asynchronous reset (MR) input resets the shift register at low level, simplifying the control logic.

　　5.100 MHz Typical Shift Output Frequency: Supports high-speed data shift operations for high-performance applications.

　　6. Input level compatibility: 74HC595D supports CMOS level, 74HCT595D supports TTL level, adapting to different logic circuits.

　　7. ESD protection: Compliant with HBM JESD22-A114F standard (more than 2000 V) and MM JESD22-A115-A standard (more than 200 V), which improves the reliability of the device.

　　8. Multiple Package Options: Different package options are available to suit a variety of applications.

　　9. Wide operating temperature range: Operating temperature ranges of -40°C to +85°C and -40°C to +125°C for harsh environments.

　　Application Scenarios

　　1. Serial to Parallel Data Conversion: Converts serial input data to parallel output, suitable for a variety of data transmission and processing systems.

　　2. Remote Control Holding Registers: Provide stable and reliable storage in remote control and data holding applications.

　　Operating Principle

　　The shift registers of the 74HC595D and 74HCT595D receive data via the serial input (DS) and shift the data via a low-to-high level transition of the shift clock (SHCP). The storage register clock (STCP) controls the transfer of data from the shift register to the storage register. The output enable input (OE) determines whether storage register data appears at the output.
