74LV164D,112

Overview

The 74LV164D,112 is an 8-bit serial-in/parallel-out shift register manufactured by Nexperia. It features two serial data inputs (DSA and DSB) and eight parallel outputs (Q0 to Q7). Data shifts on the LOW-to-HIGH clock transition, with an active LOW master reset input. The device operates within a supply voltage range of 1.0 V to 5.5 V and supports temperatures from -40 °C to +125 °C. Propagation delay is typically 12 ns at 3.3 V. It utilizes CMOS technology for low power dissipation and includes input clamp diodes.

Feature Summary

• Gated serial data inputs allow either input to function as an active HIGH enable for the other.
• Asynchronous master reset clears the register and forces all outputs LOW independently of other inputs.
• Input clamp diodes enable interface to voltages exceeding VCC using current limiting resistors.

Applications

• Low-voltage logic applications requiring serial-to-parallel conversion
• Mixed voltage systems utilizing TTL input levels between VCC = 2.7 V and VCC = 3.6 V
• Bus-oriented data storage and transfer circuits

Procurement Notes

Verify component authenticity through authorized Nexperia channels or certified distributors. Confirm package marking matches SOIC-14 specifications. Check datasheet revision history for updates regarding ESD protection standards and operating conditions. Ensure design compliance with absolute maximum ratings to prevent permanent damage.

Selection Notes

Select this component for designs requiring wide supply voltage compatibility from 1.0 V to 5.5 V. Consider the SOIC-14 package for surface-mount assembly. Evaluate propagation delay requirements against specific clock frequencies. Verify thermal performance within the -40 °C to +125 °C operating range for industrial environments.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices. It implements standard 8-bit shift register functionality compatible with JEDEC standards for various voltage ranges. The 'D' suffix indicates the SOIC-14 plastic small outline package variant.

Replacement Considerations

74LV164PW: TSSOP14 package variant. 74LV164BQ: DHVQFN14 package variant. These share identical electrical characteristics but differ in physical footprint and pinout dimensions.
