74LV164D-Q100J

Overview

The Nexperia 74LV164D-Q100J is an automotive-qualified, 8-bit serial-in/parallel-out shift register. It operates within a supply voltage range of 1.0 V to 5.5 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. The device features gated serial data inputs (DSA, DSB) and an asynchronous master reset (MR). Data shifts on the LOW-to-HIGH clock transition. It is housed in a SO14 plastic small outline package (SOT108-1) and is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standards
• Wide operating voltage range supporting low-voltage applications down to 1.0 V
• Gated serial data inputs allowing flexible entry configurations
• Asynchronous master reset function that overrides all other inputs

Applications

• Automotive electronic systems requiring high reliability
• Industrial control logic circuits
• Data storage and transfer applications

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm the temperature grade aligns with system requirements. Ensure ESD protection specifications meet design safety margins. Check RoHS compliance status against regulatory needs. Validate pinout compatibility during PCB layout integration.

Selection Notes

Select this component when an 8-bit shift register with parallel output is needed for automotive environments. Consider the wide voltage tolerance for mixed-signal interfaces. Evaluate the asynchronous reset capability for system initialization needs. Compare propagation delays against clock speed requirements at the target supply voltage.

Part Context

This part belongs to the Nexperia 74LV164-Q100 family of automotive-grade logic devices. The 'D' designation indicates the SO14 package variant. The '-Q100' suffix confirms adherence to automotive quality standards. This series provides robust performance for harsh operating conditions.

Replacement Considerations

Check for equivalent parts with identical pinouts and electrical characteristics. Verify that alternative suppliers offer matching AEC-Q100 qualification. Ensure functional compatibility regarding reset behavior and clock edge triggering.
