74HC14PW,112

Overview

The Nexperia 74HC14PW,112 is a hex inverting Schmitt trigger manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and features CMOS low power dissipation with high noise immunity. The device includes clamp diodes on inputs for interfacing voltages exceeding VCC. It complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V). ESD protection exceeds 2000 V HBM and 1000 V CDM. Latch-up performance exceeds 100 mA per JESD 78 Class II Level B. It is specified for ambient temperatures from -40 °C to +85 °C and up to +125 °C.

Feature Summary

• Schmitt-trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• Inputs include clamp diodes enabling interface to voltages in excess of VCC
• High noise immunity and unlimited input rise and fall times

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the component meets all necessary environmental compliance standards for the intended application. Ensure design parameters align with the recommended operating conditions provided in the official datasheet before finalizing procurement.

Selection Notes

Select this component when slow input signal transitions require conditioning via Schmitt-trigger action. It is suitable for applications needing high noise immunity and low static power consumption. Verify compatibility with system voltage levels and ensure thermal management accounts for total power dissipation limits at maximum operating temperatures.

Part Context

This part belongs to the 74HC logic family, characterized by wide supply voltage operation and CMOS technology. It serves as a digital logic inverter with hysteresis. The PW suffix indicates a TSSOP14 plastic thin shrink small outline package. It is designed for general-purpose digital switching and signal conditioning tasks in electronic circuits.

Replacement Considerations

The 74HCT14PW variant offers TTL-compatible input levels while maintaining the same pinout and functionality. Other packages such as SO14 or DHVQFN14 provide alternative form factors for the same logical function.
