74LV14BQ,115

Inverter Gates Overview

The Nexperia 74LV14BQ,115 is a hex inverting Schmitt trigger implemented in low-voltage Si-gate CMOS technology. It operates within a supply voltage range of 1.0 V to 5.5 V and is housed in a DHVQFN14 (SOT762-1) package with dimensions of 2.5 × 3 × 0.85 mm. The device provides six independent inverting buffers with distinct positive-going (VT+) and negative-going (VT-) switching thresholds to generate jitter-free outputs from slowly changing signals. It supports an ambient temperature range of -40 °C to +125 °C.

Inverter Gates Feature Summary

• Provides input hysteresis to transform slowly-changing signals into sharply defined output waveforms
• Accepts TTL input levels when the supply voltage is between 2.7 V and 3.6 V
• Includes I_OFF circuitry to prevent backflow current during partial power-down conditions
• Compatible with 74HC14 and 74HCT14 pinouts and functions

Inverter Gates Applications

• Wave and pulse shapers for highly noisy environments
• Astable multivibrators
• Monostable multivibrators

Inverter Gates Procurement Notes

Verify that the ordering suffix ',115' corresponds to the DHVQFN14 package (SOT762-1). Confirm the required temperature grade (-40 °C to +125 °C) matches the specific datasheet revision. Ensure design compatibility with the specified supply voltage limits and check if ESD protection ratings meet system requirements.

Inverter Gates Selection Notes

Select this component when slow-rising input signals require noise immunity through Schmitt-trigger action. It is suitable for applications needing TTL level translation at 3.3 V operation. Verify that the DHVQFN14 package size fits the PCB layout constraints and that the thermal dissipation characteristics are adequate for the operating environment.

Inverter Gates Part Context

This part belongs to the 74LV logic family, designed for low-voltage digital applications. It serves as a direct functional replacement for standard 74HC14 and 74HCT14 devices while offering improved performance at lower supply voltages. The BQ suffix specifically denotes the leadless DHVQFN package variant.

Inverter Gates Replacement Considerations

The 74LV14D and 74LV14PW are functionally equivalent alternatives using SO14 and TSSOP14 packages respectively.
