74LV164BQ-Q100X

Overview

The Nexperia 74LV164BQ-Q100X is an automotive-qualified, 8-bit serial-in/parallel-out shift register housed in a DHVQFN14 package (SOT762-1). It operates on a wide supply voltage range from 1.0 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features gated serial data inputs (DSA, DSB) where either input acts as an active HIGH enable for the other. Data shifts on the LOW-to-HIGH clock transition, while an asynchronous master reset (MR) clears outputs. It accepts TTL levels between 2.7 V and 3.6 V.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Wide operating voltage range supporting low-voltage applications down to 1.0 V
• Asynchronous master reset overrides all inputs to clear the register
• Gated serial data inputs allow flexible configuration of data entry

Applications

• Automotive engine control units
• Body control modules
• Transmission control units

Procurement Notes

Verify the specific suffix 'BQ' corresponds to the DHVQFN14 package (SOT762-1) rather than SO14 or TSSOP14 variants. Confirm that the Q100 designation ensures compliance with AEC-Q100 Grade 1 requirements for your target automotive environment. Ensure design safeguards account for the specified absolute maximum ratings to prevent permanent damage.

Selection Notes

Select this component when an 8-bit shift register is required for automotive environments demanding high reliability and wide voltage tolerance. The LV series offers lower power consumption compared to standard logic families. Verify that the DHVQFN14 package dimensions fit the PCB layout constraints and that the thermal dissipation characteristics meet the application's power budget.

Part Context

This part belongs to the Nexperia 74LV164-Q100 family of automotive-grade logic devices. The family includes variants in different packages such as SO14 and TSSOP14. All members share the same functional description and electrical characteristics but differ in physical footprint and thermal properties. The BQ suffix specifically identifies the leadless DHVQFN package option.

Replacement Considerations

Direct pin-compatible replacements within the same package require checking the specific logic family voltage compatibility. Other manufacturers may offer equivalent 8-bit shift registers, but automotive qualification must be verified independently.
