74HC7014N,112

Overview

The 74HC7014N,112 is a hex non-inverting precision Schmitt-trigger buffer 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 input trigger levels defined between 0.55 × VCC and 0.65 × VCC, ensuring high noise immunity. Static characteristics include a maximum low-level output voltage of 0.4 V at 5.2 mA (VCC = 4.5 V) and a maximum high-level output voltage of 3.7 V at -5.2 mA (VCC = 6.0 V). Dynamic performance specifies a maximum propagation delay of 175 ns at VCC = 4.75 V.

Feature Summary

• Hex non-inverting buffer with precision Schmitt-trigger inputs for jitter-free signal transformation
• High noise immunity suitable for highly noisy environments due to precisely defined trigger windows
• Robust ESD protection exceeding 2000 V (HBM Class 2) and 1000 V (CDM Class C3)
• Input shorts allowed to -1.5 V and +16 V without disturbing other channels

Applications

• Wave and pulse shapers for highly noisy environments
• Signal conditioning where slowly changing input signals require sharp output transitions
• Digital logic interfacing requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix '112' against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure the procurement source provides the correct datasheet revision (Rev. 6 or later) to match the specified operating conditions and electrical characteristics. Confirm RoHS compliance status as detailed in the manufacturer's product data sheet.

Selection Notes

Select this component when designing circuits that require precise threshold definition and high noise rejection. The wide supply voltage range allows compatibility with various digital logic families. Verify that the required propagation delay and output drive capabilities meet the system timing constraints under the intended operating temperature and load conditions.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It functions as a hex buffer with Schmitt-trigger inputs, distinct from standard buffers by its hysteresis properties. The device is designed for general-purpose digital applications where signal integrity in noisy environments is critical. It complies with JEDEC standard no. 7A.

Replacement Considerations

Compatible substitutes include the 74HC7014 from NXP Semiconductors and other manufacturers offering equivalent hex Schmitt-trigger buffers. Verify pinout compatibility and electrical parameter alignment before substitution.

FAQ

What are the specific trigger level thresholds for the 74HC7014?

The precisely defined trigger levels lie in a window between 0.55 × VCC and 0.65 × VCC.

How does the device handle input shorts?

Inputs can be shorted to -1.5 V and +16 V without disturbing other channels, and they include clamp diodes to interface with voltages in excess of VCC using current limiting resistors.
