74HC14DB,112

Overview

The Nexperia USA Inc. 74HC14DB,112 is a hex inverting Schmitt trigger integrated circuit manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features six independent inverters with Schmitt-trigger inputs that transform slowly changing signals into sharply defined outputs. It includes input clamp diodes for interfacing with voltages exceeding VCC. The component utilizes a 14-lead plastic small outline package (SO14) with a body width of 3.9 mm.

Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow input rise and fall times
• CMOS technology ensures low power dissipation across the entire operating voltage range
• Input clamp diodes enable safe interfacing to voltages higher than the supply voltage using current limiting resistors
• ESD protection exceeds 2000 V according to Human Body Model standards

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SO14 package variant when sourcing. Confirm RoHS compliance status and check for any product change notices regarding marking or packaging updates prior to finalizing procurement orders.

Selection Notes

Select this component for designs requiring signal conditioning with hysteresis to eliminate jitter on noisy lines. Ensure the application voltage remains within the 2.0 V to 6.0 V range. Consider the thermal derating characteristics if operating near the upper temperature limits.

Part Context

This part belongs to the 74HC logic family, which offers CMOS performance with pin compatibility to Low-power Schottky TTL. The 'DB' designation indicates the specific SO14 package type. It serves as a standard solution for digital signal inversion and waveform shaping in general-purpose electronic circuits.

Replacement Considerations

Public confirmed substitute part numbers include 74HC14PW,118.
