74AHC595D-Q100,118

Shift Registers Overview

The Nexperia 74AHC595D-Q100,118 is an automotive-grade 8-bit serial-in/serial-out or parallel-out shift register with output latches. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features balanced propagation delays, Schmitt trigger inputs, and overvoltage tolerant inputs up to 5.5 V. It includes separate clocks for the shift and storage registers, an asynchronous reset input, and high noise immunity.

Shift Registers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Separate clocks for shift and storage registers
• Overvoltage tolerant inputs to 5.5 V

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the component meets the AEC-Q100 Grade 1 qualification requirements for your target application. Ensure compatibility with the intended operating temperature range and supply voltage specifications before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage and shift clocking is required. It is suitable for mixed-voltage environments due to its overvoltage tolerant inputs. Consider the SO16 package dimensions and thermal characteristics for PCB layout planning.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC_AHCT595-Q100 family of logic ICs. It is designed for automotive applications requiring high reliability and wide operating temperature ranges. The device provides serial-to-parallel conversion capabilities with output latching functionality.

Shift Registers Replacement Considerations

Check for pin-compatible alternatives such as the 74AHCT595D-Q100 if TTL input levels are preferred. Verify electrical characteristics match the original design requirements when substituting.

Shift Registers FAQ

What is the function of the MR input?

The MR (Master Reset) input is active LOW and resets the shift register asynchronously.

How does the OE input affect the outputs?

When OE is HIGH, the outputs assume a high-impedance OFF-state. When OE is LOW, data from the storage register appears at the outputs.
