74AHC164BQ,115

Overview

The Nexperia 74AHC164BQ,115 is an 8-bit serial-in/parallel-out shift register housed in a DHVQFN14 package (SOT762-1). It operates on a supply voltage range of 2.0 V to 5.5 V with inputs tolerant up to 5.5 V. The device features two serial data inputs (DSA and DSB) and eight parallel outputs (Q0-Q7), shifting data on LOW-to-HIGH clock transitions. A master reset input clears the register. Static characteristics include low leakage current and high noise immunity.

Feature Summary

• Features Schmitt-trigger actions on all inputs for improved noise immunity
• Includes overvoltage tolerant inputs allowing use as translators in mixed voltage environments
• Provides balanced propagation delays and CMOS low power dissipation

Applications

• Serial-to-parallel data conversion circuits
• Mixed voltage level translation interfaces
• General-purpose shift register logic applications

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets RoHS3 compliance standards for your manufacturing process. Ensure the design accounts for the thermal dissipation requirements specified for the DHVQFN14 package during operation.

Selection Notes

Select this component when an 8-bit shift register is required in a leadless surface-mount package. The AHC series offers wide voltage compatibility compared to standard HC logic. Verify that the application does not require automotive qualification, as this product is not designated for such use.

Part Context

This part belongs to the 74AHC logic family, utilizing high-speed Si-gate CMOS technology. It is pin-compatible with Low-power Schottky TTL devices. The BQ suffix indicates the DHVQFN14 package type, designed for PCB space saving while maintaining electrical performance across industrial temperature ranges.

Replacement Considerations

The 74AHCT164BQ,115 serves as a functional substitute within the same package, differing primarily in input logic levels which are TTL compatible rather than CMOS.
