74LVC14APW

Inverter Gates Overview

The 74LVC14APW is a hex inverting Schmitt trigger with 5 V tolerant input, manufactured by NXP Semiconductors. It operates within a supply voltage range of 1.2 V to 3.6 V and supports an input voltage up to 5.5 V. The device features six independent inverters with distinct positive-going (VT+) and negative-going (VT-) switching thresholds, creating hysteresis for noise immunity. It is housed in a TSSOP14 plastic thin shrink small outline package (SOT402-1) with 14 leads and a body width of 4.4 mm. The component is specified for ambient temperatures from -40 °C to +125 °C.

Inverter Gates Feature Summary

• Provides six inverting buffers with Schmitt trigger action to transform slowly changing signals into sharply defined outputs
• Features 5 V tolerant inputs allowing direct interfacing with 5 V logic devices while operating at lower voltages
• Includes high electrostatic discharge protection exceeding specified limits for Human Body Model, Machine Model, and Charged Device Model

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP14 package variant SOT402-1 when sourcing. Confirm the temperature grade matches the required operational range of -40 °C to +125 °C. Ensure compatibility with the target supply voltage range of 1.2 V to 3.6 V. Check for RoHS compliance status as indicated in the product data sheet revision history.

Inverter Gates Selection Notes

Select this component when signal integrity requires noise filtering via hysteresis in low-voltage digital circuits. It is suitable for translating signals between 3.3 V and 5 V domains due to its input tolerance. Consider the TSSOP14 package constraints regarding thermal dissipation and board space. Verify that the propagation delay characteristics meet the timing requirements of the specific application frequency.

Inverter Gates Part Context

This part belongs to the 74LVC14A family of hex inverting Schmitt triggers. Other available packages include SO14 (SOT108-1), SSOP14 (SOT337-1), and DHVQFN14 (SOT762-1). The device is part of the LVC/LCX/Z series designed for low-power CMOS applications. It complies with JEDEC standards JESD8-C and JESD36 for operation within the 2.7 V to 3.6 V supply range.

Inverter Gates Replacement Considerations

Direct functional substitutes within the same package include other manufacturers' 74LVC14 variants. Cross-reference pinouts and electrical specifications carefully. Ensure any replacement maintains the 5 V input tolerance and Schmitt trigger hysteresis characteristics required for the application.
