74LV164PW,118

Overview

The Nexperia 74LV164PW,118 is an 8-bit serial-in/parallel-out shift register housed in a TSSOP14 (SOT402-1) package. It operates within a supply voltage range of 1.0 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features two gated serial data inputs (DSA, DSB), eight parallel outputs (Q0-Q7), and an asynchronous active LOW master reset (MR). Data shifts on the LOW-to-HIGH clock transition. Propagation delay ranges from 9 ns to 39 ns depending on voltage. Input leakage is 1.0 μA max at 5.5 V.

Feature Summary

• Gated serial data inputs allow either input to function as an enable for the other.
• Asynchronous master reset clears all outputs independently of the clock signal.
• CMOS low power dissipation optimized for low-voltage applications between 1.0 V and 3.6 V.
• Input clamp diodes permit interfacing with voltages exceeding VCC using current limiting resistors.

Applications

• Serial-to-parallel data conversion
• Status indication systems
• LED driving circuits

Procurement Notes

Verify the ordering suffix '118' corresponds to the TSSOP14 package variant. Confirm RoHS compliance status via official documentation. Ensure the application environment remains within the specified -40 °C to +125 °C temperature range. Check that supply voltage does not exceed 5.5 V or drop below 1.0 V during operation.

Selection Notes

Select this component when an 8-bit shift register with parallel output is required. The LV series offers wide voltage compatibility compared to standard logic families. Verify that the TSSOP14 package fits the PCB layout constraints. Consider the propagation delay specifications relative to the system clock frequency requirements.

Part Context

This part belongs to the Nexperia 74LV logic family, designed for low-voltage CMOS applications. It provides high noise immunity and compatibility with TTL levels at specific supply voltages. The PW suffix indicates the plastic thin shrink small outline package, distinguishing it from SO or QFN variants within the same logical function.

Replacement Considerations

Direct pin-compatible replacements include the 74LV164D (SO14 package) and 74LV164BQ (DHVQFN14 package). These share identical electrical characteristics and functionality but differ in physical package dimensions and thermal properties.
