74AHC14PW,118

Overview

The Nexperia 74AHC14PW,118 is a hex inverting Schmitt trigger integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes a TSSOP14 package (SOT402-1) with 14 leads and a body width of 4.4 mm. It provides balanced propagation delays and high noise immunity suitable for mixed-voltage environments. The component supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Hex inverter configuration with Schmitt-trigger inputs for signal conditioning
• Overvoltage tolerant inputs allowing operation in mixed voltage systems
• High noise immunity and balanced propagation delays
• ESD protection compliant with ANSI/ESDA/JEDEC standards

Applications

• Signal translation between mixed voltage logic levels
• Waveform shaping of slowly changing input signals
• Relaxation oscillator circuits
• Jitter-free output signal generation

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the TSSOP14 package variant SOT402-1 as documented in the official datasheet. Confirm that the procurement channel sources directly from Nexperia or authorized distributors to ensure product authenticity. Cross-reference the RoHS compliance status and environmental declarations against the latest manufacturer documentation prior to finalizing orders.

Selection Notes

Select this component when designing circuits requiring precise threshold control via Schmitt-trigger action to eliminate signal noise. The wide supply voltage range accommodates various digital logic families. Ensure the application environment remains within the specified -40 °C to +125 °C temperature limits. Verify that input signal rise and fall times do not exceed the device's switching capabilities for optimal performance.

Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices produced by Nexperia. It serves as a functional equivalent to standard hex inverters but includes hysteresis for improved noise rejection. The PW suffix indicates the Thin Shrink Small Outline Package, distinguishing it from SOIC or QFN variants within the same logical family.

Replacement Considerations

Direct pin-compatible replacements include other manufacturers' 74AHC14 equivalents in TSSOP14 packages. Verify that substitute components maintain identical Schmitt-trigger thresholds and ESD protection ratings. Check for any differences in propagation delay specifications or power dissipation characteristics before implementation.

FAQ

What is the function of the Schmitt-trigger inputs?

The Schmitt-trigger inputs transform slowly changing input signals into sharply defined, jitter-free output signals by providing distinct positive-going and negative-going threshold voltages.

Can this device be used for voltage translation?

Yes, the overvoltage tolerant inputs allow the use of these devices as translators in mixed voltage environments, accepting input voltages up to 5.5 V regardless of the supply voltage.

What is the maximum operating temperature?

The device is specified for an ambient temperature range from -40 °C to +125 °C.
