74LV164DB,112

Overview

The Nexperia 74LV164DB,112 is an 8-bit serial-in/parallel-out shift register housed in a SO14 plastic small outline package (SOT108-1). 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. The device operates with a supply voltage range of 1.0 V to 5.5 V and supports temperatures from -40 °C to +125 °C.

Feature Summary

• Features gated serial data inputs where either input acts as an active HIGH enable for the other.
• Includes an asynchronous master reset input that clears the register and forces all outputs LOW.
• Inputs include clamp diodes allowing interface to voltages exceeding VCC using current limiting resistors.

Applications

• Low-voltage logic applications requiring serial-to-parallel conversion
• Systems utilizing TTL input levels between VCC = 2.7 V and VCC = 3.6 V
• Industrial environments requiring extended temperature operation up to +125 °C

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the tube packaging format required for your assembly process. Confirm the component status with the manufacturer, as production availability may change. Ensure the SO14 package dimensions align with your PCB footprint design before finalizing procurement orders.

Selection Notes

Select this component when an 8-bit shift register is needed with a wide 1.0 V to 5.5 V operating range. It is suitable for mixed-voltage systems due to its ability to accept TTL levels at lower supply voltages. Consider the SO14 package if surface mount space allows for standard leaded footprints rather than shrink packages.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. The 'DB' designation specifically identifies the SO14 package variant within the broader 74LV164 family, which also includes TSSOP and DHVQFN options. It serves as a fundamental building block for digital data storage and transfer circuits.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers' 74LV164 equivalents based on pinout and electrical specifications.
