General description

The 74LV14 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC14 and 74HCT14.

The 74LV14 provides six inverting buffers with Schmitt-trigger input. It is capable of transforming slowly-changing input signals into sharply defined, jitter-free output signals.

The inputs switch at different points for positive and negative-going signals. The difference between the positive voltage VT+ and the negative voltage VT- is defined as the input hysteresis voltage VH.

  • Typical output ground bounce < 0.8 V at VCC = 3.3 V and Tamb = 25 Cel
  • Typical HIGH-level output voltage (VOH) undershoot: > 2 V at VCC = 3.3 V and Tamb = 25 Cel
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Multiple package options
  • Specified from -40 Cel to +85 Cel and from -40 Cel to +125 Cel
