74HC7014D/C4J

Overview

The Nexperia 74HC7014D/C4J 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 3.00 V, tPHL is up to 475 ns and tPLH is up to 175 ns; at 6.00 V, tPHL is up to 73 ns and tPLH is up to 46 ns.

Feature Summary

• Precision Schmitt-trigger inputs transform slowly changing signals into sharply defined jitter-free outputs.
• High noise immunity suitable for operation in highly noisy environments.
• Input clamp diodes allow interfacing to voltages exceeding VCC using current limiting resistors.

Applications

• Wave and pulse shapers for highly noisy environments

Procurement Notes

Verify the specific suffix 'C4J' against official Nexperia documentation to confirm its exact meaning regarding tape-and-reel specifications or marking variations. Ensure the ordered component matches the SO14 package type and temperature range requirements specified in the datasheet before finalizing procurement.

Selection Notes

Select this component when precise threshold control is required to eliminate signal jitter in noisy circuits. The wide supply voltage range and robust input protection make it suitable for industrial applications where signal integrity must be maintained despite environmental interference or slow-rising input waveforms.

Part Context

This part belongs to the 74HC logic family, characterized by CMOS low power dissipation and compatibility with standard digital systems. As a hex buffer, it contains six independent non-inverting channels, providing significant drive capability while maintaining symmetrical output impedance and balanced propagation delays across all channels.

Replacement Considerations

Direct replacements include the 74HC7014D/118 or 74HC7014D,653. Verify that any substitute maintains the same SO14 package outline and meets the required operating temperature range of -40 °C to +125 °C.
