Nexperia Energy Harvesting Solutions(Nowi) 74HCT595D Environmental and export classification status description

The 74HCT595D is an 8-bit shift register with an output latch, operated by the high-speed TTL (Transistor-Transistor Logic) interface. The device is designed to facilitate the shift-in and shift-out of serial data, allowing for effective data management in digital circuits. Functions - Data Shifting: The 74HCT595D shifts data into the register on the rising edge of the clock signal. - Data Latching: The state of the shift register is latched when the latch enable (LE) pin is activated. This allows for stable outputs. - Serial to Parallel Conversion: It converts serial input data into parallel output, making it useful in many digital applications. - Output Control: The device includes a tri-state output configuration, which allows for flexible control of the output pins. Applications - LED Driver Circuits: Commonly used for controlling multiple LEDs, allowing for more compact designs. - Data Communication: Serves as a buffer and expands data lines in communication interfaces. - Microcontroller Interfacing: Used for interfacing microcontrollers with various peripheral devices in embedded systems. - Display Control: Facilitates the control of seven-segment displays and other multiplexed outputs. Alternative Parts - 74HC595: Similar functionality but with a higher speed and power characteristics suitable for CMOS circuits. - 74LS595: A low-power version that operates similarly but is based on low-power TTL technology. - 74HCT164: A similar 8-bit shift register without an output latch. - SN74HCT595: Texas Instruments' equivalent which offers the same basic functionalities. Embedded Modules - Shift Register Expanders: Modules based on the 74HC595 for Arduino or Raspberry Pi for controlling multiple outputs. - LED Matrix Driver Modules: Often integrated in LED matrix display setups for controlling multiple rows and columns. - Interfacing Boards: General-purpose boards that integrate the 74HCT595 to expand GPIO pins on microcontrollers.
