74HC14D

Hex inverting Schmitt trigger

The 74HC14; 74HCT14 is a hex inverter with Schmitt-trigger inputs. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals.

Features and benefits

  • Wide supply voltage range from 2.0 to 6.0 V

  • CMOS low power dissipation

  • High noise immunity

  • Unlimited input rise and fall times

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

  • Complies with JEDEC standards:

    • JESD8C (2.7 V to 3.6 V)

    • JESD7A (2.0 V to 6.0 V)

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Multiple package options

  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C

Applications

  • Wave and pulse shapers

  • Astable multivibrators

  • Monostable multivibrators

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
