74LV164BQ,115

Overview

The Nexperia 74LV164BQ,115 is an 8-bit serial-in/parallel-out shift register housed in a DHVQFN14 (SOT762-1) 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 master reset (MR). Data shifts on the LOW-to-HIGH clock transition. Static characteristics include input leakage current up to 1.0 μA at 5.5 V and additional supply current per switching input up to 850 μA.

Feature Summary

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

Applications

• Serial-to-parallel data conversion
• Parallel output expansion
• Digital signal processing

Procurement Notes

Verify the ordering suffix matches the required temperature range and package variant. Confirm RoHS compliance status via official documentation. Ensure design accounts for power dissipation derating specific to the DHVQFN14 package above 98 °C. Validate ESD protection levels against application requirements.

Selection Notes

Select this component for low-voltage CMOS applications requiring wide supply flexibility. The LV series accepts TTL input levels between 2.7 V and 3.6 V. Consider the DHVQFN14 package for space-constrained surface-mount designs. Verify operating temperature range meets environmental specifications.

Part Context

This part belongs to the 74LV logic family, characterized by low voltage operation and CMOS technology. The BQ suffix denotes the DHVQFN14 plastic dual in-line compatible thermal enhanced very thin quad flat package with no leads. It is manufactured by Nexperia USA Inc.
