74HC7014

Hex non-inverting precision Schmitt-trigger

The 74HC7014 is a hex buffer with precision Schmitt-trigger inputs. The precisely defined trigger levels are lying in a window between 0.55 × VCC and 0.65 × VCC. It makes the circuit suitable to operate in a highly noisy environment. Input shorts are allowed to -1.5 V and +16 V without disturbing other channels. Inputs 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.

特性

  • Wide supply voltage from 2.0 V to 6.0 V

  • CMOS low power dissipation

  • High noise immunity

  • Unlimted input rise and fall times

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

  • Complies with JEDEC standard no. 7A

  • ESD protection:

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

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

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

目标应用

  • Wave and pulse shapers for highly noisy environments
