74LV14D,118

Inverter Gates Overview

The Nexperia 74LV14D,118 is a hex inverting Schmitt trigger manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.0 V to 5.5 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. The device features six inverting buffers with Schmitt-trigger inputs that transform slowly changing signals into sharply defined outputs. It complies with JEDEC standards for various voltage ranges including JESD8-7, JESD8-5, JESD8C, and JESD36. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). The component is specified for ambient temperatures from -40 °C to +125 °C and utilizes an SO14 plastic small outline package.

Inverter Gates Feature Summary

• Provides six inverting buffers with Schmitt-trigger input action
• Capable of transforming slowly-changing input signals into sharply defined, jitter-free output signals
• Accepts TTL input levels when operating between 2.7 V and 3.6 V supply voltages
• Complies with multiple JEDEC standards across the full supply voltage range

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LV14 series includes SO14, TSSOP14, and DHVQFN14 options. Confirm temperature range specifications align with application requirements, noting the D variant supports up to +125 °C. Ensure design accounts for additional power dissipation caused by slow input rise and fall times during operation.

Inverter Gates Selection Notes

Select this component for applications requiring noise immunity through hysteresis and signal regeneration. It serves as a pin and function compatible replacement for 74HC14 and 74HCT14 devices while offering optimized performance for low voltage applications ranging from 1.0 V to 3.6 V. Consider the wide supply voltage capability when interfacing with different logic families.

Inverter Gates Part Context

The 74LV14 belongs to the LV (Low Voltage) logic family from Nexperia, designed for CMOS low power dissipation. It is part of a broader portfolio of hex inverters and Schmitt triggers. The 'D' designation specifically identifies the SO14 package variant, distinguishing it from other package options like PW or BQ within the same logical function family.

Inverter Gates Replacement Considerations

The datasheet explicitly states the 74LV14 is pin and function compatible with 74HC14 and 74HCT14.
