Overview
The 74HCT595D-Q100,118 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs, manufactured by Nexperia USA Inc. This component is part of the 74HCT595-Q100 series, which is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications. The device features separate clocks for the shift and storage registers, a serial input (DS), a serial output (Q7S) for cascading, and an asynchronous reset MR input. The outputs are tri-state, allowing them to be set to a high-impedance OFF-state when the output enable input (OE) is HIGH.

Q & A
- What is the primary function of the 74HCT595D-Q100,118?
The primary function is to act as an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.
- What are the operating voltage and temperature ranges for this component?
The operating voltage range is 4.5 V to 5.5 V, and the operating temperature range is -40°C to 125°C.
- What logic family does the 74HCT595D-Q100,118 belong to?
The 74HCT595D-Q100,118 belongs to the TTL (Transistor-Transistor Logic) family.
- What type of outputs does this component have?
The component has tri-state outputs.
- What is the significance of AEC-Q100 qualification?
AEC-Q100 qualification indicates that the component meets the Automotive Electronics Council standards for automotive applications, specifically Grade 1.
- How does the shift register and storage register operate in this component?
The shift register and storage register have separate clocks. Data is shifted on the LOW-to-HIGH transitions of the SHCP input and transferred to the storage register on a LOW-to-HIGH transition of the STCP input.
- What is the purpose of the OE (Output Enable) input?
The OE input controls the output state; when OE is LOW, the outputs are active, and when OE is HIGH, the outputs assume a high-impedance OFF-state.
- What kind of ESD protection does this component offer?
The component offers ESD protection exceeding 2000 V for HBM (Human Body Model) and 1000 V for CDM (Charged Device Model).
- Can this component be used in non-automotive applications?
Yes, while it is qualified for automotive use, it can also be used in industrial and consumer electronics requiring shift register functionality.
- What package options are available for the 74HCT595-Q100 series?
The 74HCT595-Q100 series is available in multiple packages, including DHVQFN, SO16, and TSSOP16.
- How can I purchase the 74HCT595D-Q100,118?
You can purchase this component through Nexperia's official distributors or directly from Nexperia's sales organization.
