74LV164D,118

Overview

The Nexperia 74LV164D,118 is an 8-bit serial-in/parallel-out shift register housed in a SO14 plastic small outline package (SOT108-1). It operates within a supply voltage range of 1.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features two gated serial data inputs (DSA and DSB) that allow either input to act as an active HIGH enable for the other. Data shifts on the LOW-to-HIGH clock transition, while an asynchronous master reset clears all outputs to LOW independently of other inputs.

Feature Summary

• Gated serial data inputs allowing flexible configuration where one input enables data entry through the other
• Asynchronous master reset function that forces all parallel outputs LOW regardless of clock or data states
• Input clamp diodes permitting interface to voltages exceeding VCC when current limiting resistors are used

Applications

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

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the tube packaging format defined in the official datasheet. Confirm the component status remains active production rather than obsolete or end-of-life. Ensure the SO14 package variant matches the required PCB footprint dimensions specified in the SOT108-1 outline drawing.

Selection Notes

Select this component for designs requiring low power CMOS dissipation across a wide voltage spectrum. It is suitable for applications needing high ESD protection performance exceeding 2000 V HBM. Consider the propagation delay characteristics relative to the maximum operating frequency requirements of the target system.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. It functions as a fundamental building block for digital data handling, specifically converting serial bit streams into parallel output formats. The device adheres to JEDEC standards for various voltage domains including 1.65 V, 2.3 V, 2.7 V, and 5.5 V systems.

Replacement Considerations

The 74LV164PW serves as a pin-compatible alternative utilizing the TSSOP14 package.
