74LV14DB,118

Inverter Gates Overview

The Nexperia 74LV14DB,118 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 provides six independent inverting buffers with Schmitt-trigger inputs. The device transforms slowly changing input signals into sharply defined, jitter-free output signals by utilizing distinct positive and negative-going switching thresholds. It features pin and function compatibility with 74HC14 and 74HCT14 families.

Inverter Gates Feature Summary

• Provides hysteresis through separate positive and negative-going input switching points to eliminate signal jitter
• Accepts TTL input levels when the supply voltage is between 2.7 V and 3.6 V
• Includes latch-up protection exceeding 100 mA per JESD 78 Class II Level B
• Offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify that the ordering suffix matches the specific package requirements, as the 74LV14 family includes multiple variants such as TSSOP14 and DHVQFN14. Confirm the temperature range specification aligns with the application environment, noting that this part supports extended ranges up to +125 °C. Ensure design compliance with the absolute maximum ratings to prevent permanent damage from overvoltage or excessive current stress.

Inverter Gates Selection Notes

Select this component when slow-rising input signals require conditioning to prevent multiple output transitions. It serves as a direct replacement for 74HC14 and 74HCT14 devices in designs requiring lower power consumption or wider supply voltage flexibility. Consider the SO14 plastic small outline package dimensions when finalizing PCB layout constraints.

Inverter Gates Part Context

This device belongs to the 74LV series of low-voltage CMOS logic components manufactured by Nexperia. It is designed to operate across a broad voltage spectrum, bridging the gap between traditional 5 V logic and modern low-voltage systems. The hex inverter configuration allows for complex timing circuits using a single integrated circuit.

Inverter Gates Replacement Considerations

The 74LV14 is pin and function compatible with the 74HC14 and 74HCT14 families.
