74HC7014D,112

Overview

The Nexperia 74HC7014D,112 is a hex non-inverting precision Schmitt-trigger buffer housed in an SO14 (SOT108-1) package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features precisely defined trigger levels between 0.55 × VCC and 0.65 × VCC, ensuring high noise immunity. Input shorts are permitted to -1.5 V and +16 V without disturbing other channels. Propagation delays vary with voltage: at 3.0 V, tPHL is up to 715 ns and tPLH up to 260 ns; at 6.0 V, tPHL is up to 112 ns and tPLH up to 70 ns.

Feature Summary

• Precision Schmitt-trigger inputs with defined thresholds between 0.55 × VCC and 0.65 × VCC for high noise immunity
• Unlimited input rise and fall times allowing operation in highly noisy environments
• Input shorting capability to -1.5 V and +16 V without affecting other channels
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Wave and pulse shapers for highly noisy environments

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when precise threshold definition is required to reject noise on slowly changing signals. The wide supply range accommodates various logic families. Ensure the application does not exceed the absolute maximum ratings for input clamping current or output current to prevent permanent damage.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It provides six independent non-inverting buffers with Schmitt-trigger action. The SO14 package offers a compact solution for surface-mount assembly, suitable for general-purpose digital signal conditioning where jitter-free outputs are necessary.

Replacement Considerations

Check for pin-compatible alternatives such as the 74HC7014PW if different packaging is needed. Verify that substitute parts meet the same temperature range (-40 °C to +125 °C) and ESD protection specifications.
