SN54AC14-SP Hex Schmitt-trigger Inverters |

SN54AC14-SP (ACTIVE) Hex Schmitt-trigger Inverters



These Schmitt-trigger devices contain six independent inverters. They perform the Boolean function Y = A. Because of the Schmitt action, they have different input threshold levels for positive-going (VT+) and for negative-going (VT–) signals.

These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals. They also have a greater noise margin than conventional inverters.


  • 2-V to 6-V VCC Operation
  • Inputs Accept Voltages to 6 V
  • Max tpd of 9.5 ns at 5 V
  • Rad-Tolerant: 50 kRad(Si) TID(1)
    • TID Dose Rate < 2mRad/sec
  • QML-V Qualified, SMD 5962-87624

(1) Radiation tolerance is a typical value based upon initial device qualification. Radiation Lot Acceptance Testing is available - contact factory for details.
