74LVC3G14

Triple inverting Schmitt trigger with 5 V tolerant input

The 74LVC3G14 provides three inverting buffers with Schmitt trigger input. It is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.

The inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment. Schmitt trigger action at the inputs makes the circuit tolerant of slower input rise and fall time. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

Features and benefits

  • Wide supply voltage range from 1.65 V to 5.5 V

  • 5 V tolerant input/output for interfacing with 5 V logic

  • High noise immunity

  • ±24 mA output drive (VCC = 3.0 V)

  • CMOS low power consumption

  • Latch-up performance exceeds 250 mA

  • Direct interface with TTL levels

  • Unlimited rise and fall times

  • 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 -40 °C to +125 °C.

Applications

  • Wave and pulse shaper for highly noisy environment

  • Astable multivibrator

  • Monostable multivibrator.
