74AHC164PW-Q100J

Shift Registers Overview

The Nexperia 74AHC164PW-Q100J is an 8-bit serial-in/parallel-out shift register from the AHC logic family, housed in a TSSOP14 (SOT402-1) package. It features two serial data inputs (DSA and DSB), eight parallel outputs (Q0 to Q7), and a master reset input (MR). Data shifts on LOW-to-HIGH clock transitions. The device operates with a supply voltage range of 2.0 V to 5.5 V and includes overvoltage tolerant inputs up to 5.5 V. It meets AEC-Q100 Grade 1 qualification for automotive use and functions across temperatures from -40 °C to +125 °C.

Shift Registers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Overvoltage tolerant inputs enabling use as translators in mixed voltage environments
• All inputs feature Schmitt-trigger actions for high noise immunity
• CMOS low power dissipation with balanced propagation delays

Shift Registers Applications

• Automotive applications requiring qualified logic components
• Mixed voltage environments utilizing overvoltage tolerant inputs
• Serial-to-parallel data conversion circuits
• Shift register configurations for digital signal processing

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the PW designation corresponds to the TSSOP14 form factor. Confirm that the AEC-Q100 Grade 1 qualification aligns with your system's automotive reliability standards. Ensure design parameters respect the absolute maximum ratings for supply voltage and current to prevent permanent damage. Cross-reference the datasheet revision history to confirm compatibility with your manufacturing timeline.

Shift Registers Selection Notes

Select this component when an 8-bit serial-in/parallel-out shift register is required for automotive-grade designs. The AHC series offers CMOS-level input compatibility suitable for standard logic interfaces. Consider the TSSOP14 package if space constraints allow for its body width compared to smaller alternatives like DHVQFN. Verify that the operating temperature range of -40 °C to +125 °C meets environmental requirements.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC164-Q100 family, which also includes variants in SO14 and DHVQFN packages. The 'PW' suffix specifically identifies the Thin Shrink Small Outline Package with 14 leads. The 'J' suffix typically denotes tape and reel packaging, though verification against official ordering tables is recommended. It is distinct from the AHCT version, which utilizes TTL-level input thresholds instead of CMOS levels.

Shift Registers Replacement Considerations

Direct substitutes within the same family include 74AHC164D-Q100 (SO14 package) and 74AHC164BQ-Q100 (DHVQFN package). For non-automotive applications, the standard 74AHC164 without the Q100 suffix may be considered if automotive qualification is not required.
